    What is diabetes?

    Diabetes is a chronic health condition that affects how your body processes blood sugar (glucose), the body’s main source of energy.

    After you eat, carbohydrates are broken down into glucose and released into the bloodstream. In response, the pancreas produces insulin, a hormone that allows glucose to enter the body’s cells and be used for energy.

    In people with diabetes, the body does not produce enough insulin or cannot use it properly, which causes blood sugar levels to remain too high. If not correctly diagnosed and treated, diabetes can lead to heart disease, vision loss, kidney damage and nerve injury.

    Can I make a diabetes misdiagnosis claim?

    Yes. All healthcare professionals must exercise a reasonable standard of skill and knowledge when treating you. Anything that falls beneath the accepted care standard can be seen as negligence and might entitle you to start a personal injury claim.

    As a general rule, you can make a claim for diabetes if a medical negligence solicitor can prove that:

    • A medical professional failed to meet an acceptable standard of care and breached their duty towards you.
    • That failure directly caused harm, complications or additional suffering that could have been avoided with proper diagnosis and treatment.
    • You are within the legal time limit to start your claim, which is usually 3 years.

    Examples of medical negligence that could lead to a claim for diabetes misdiagnosis

    You may be entitled to make a diabetes misdiagnosis compensation claim if a healthcare professional failed to diagnose your condition correctly, causing avoidable harm or complications. Common examples of clinical negligence in diabetes cases include:

    • The medical professional did not listen to your symptoms and made a diagnosis anyway.
    • They overlooked or dismissed clear signs of diabetes that other professionals would have recognised.
    • Errors in interpreting test results or failing to perform the necessary tests.
    • Incorrect classification of diabetes type, leading to inadequate treatment.
    • A loved one has died due to complications caused by a misdiagnosis of diabetes.
    • Going through an avoidable or unnecessary surgical procedure, such as an amputation, due to a delayed diagnosis.
    • Failure to consider atypical presentations of the condition.
    • Poor communication between healthcare professionals, resulting in overlooked information.
    • Failure by your GP to refer you to a specialist when you should have been.

    What is the time limit to make a diabetes medical negligence claim?

    Under the Limitation Act 1980, there is a general 3-year time limit to make a diabetes compensation claim from the date of the negligent treatment or the date you first became aware of the negligence.

    There are several exceptions to this rule:

    • For children, this three-year period begins on their 18th birthday, so they have until they’re 21 to make a claim. A parent or legal guardian can make a child injury claim on behalf of a minor at any time.
    • If the claimant has experienced severe side effects or cannot claim due to a pre-existing disability, the time limit is waived until they regain capacity.
    • If a loved one has passed away due to complications caused by a diabetes misdiagnosis, you have three years to start a wrongful death claim from the date of their death.

    We advise you to consult with an expert solicitor who specialises in medical negligence claims as early as possible. The sooner you seek legal advice, the easier it is to gather evidence and build a strong claim to secure compensation.

    How do I make a diabetes compensation claim?

    If you suffered because of misdiagnosis or delayed diagnosis of diabetes, you may be entitled to make a claim for compensation. This usually involved the following steps:

    Seek legal advice. Contact a specialist solicitor as soon as possible. They will assess your case to determine whether you have a valid diabetes negligence claim and explain your legal options.

    Gather evidence. Your solicitor will help collect evidence to support your claim, including:

    • Medical records and test results.
    • Witness statements, if applicable.
    • Any correspondence with the hospital or doctor who treated you.
    • Records of financial losses, such as hospital bills, medications, or lost earnings.

    Medical assessment. Your solicitor will arrange a free medical exam with a diabetes specialist. They will confirm the severity of your condition, how it was affected by the misdiagnosis, and any long-term consequences.

    Letter of claim. Your solicitor will submit a formal claim to the responsible healthcare provider or hospital, outlining your case and the compensation you seek.

    Negotiations or court proceedings. If liability is admitted, your claim will be settled without going to court (most cases). If a fair settlement cannot be reached, your solicitor may take the case to court.

    Receive your compensation. Once a settlement is agreed upon or a court decision is made, you will receive compensation. In some cases, interim payments can be arranged to help cover urgent expenses while your claim is ongoing.

    How much compensation could I claim for diabetes misdiagnosis?

    The amount of compensation awarded to you will depend on the impact of the misdiagnosis on your life. You can typically recover two types of damages in a diabetes medical negligence compensation claim:

    General damages are awarded for subjective losses, such as:

    • Physical pain and suffering.
    • Emotional and psychological distress.
    • Scarring and disfigurement.
    • Loss of enjoyment of life and amenities.

    Special damages are awarded for quantifiable financial losses, such as:

    • Private treatments and medication.
    • Past and future lost earnings.
    • The cost of hiring care and assistance with daily living.
    • Adaptations to your home or vehicle to accommodate a disability.
    • Medical aids and equipment.

    The following table provides guideline compensation amounts based on the Judicial College guidelines for diabetes misdiagnosis cases:

    Injury Type Compensation
    Loss of sight in both eyes Around £327,940
    Total loss or severe damage to both kidneys £206,730 to £256,780
    Male sterility without impotence £68,430 to £87,080
    Female infertility and sexual dysfunction £52,490 to £124,620
    Loss of bladder control or function Up to £171,680
    The amputation of several fingers £49,350 to £72,330
    The amputation of one foot £102,470 to £133,810
    Loss of one leg below the knee £119,570 to £162,290

    After a thorough review of your case, your solicitor will be able to give you an informed estimate of how much compensation you could receive for the mistreatment of diabetes.

    Can I make a diabetes misdiagnosis compensation claim with a No Win No Fee solicitor?

    Yes. If a healthcare professional breached their duty of care towards you and you are entitled to compensation, your solicitor will offer you a 100% no win no fee service*.

    Also known as a Conditional Fee Agreement, this means that the solicitor agrees to provide their services without charging any upfront fees and:

    • If you make a successful diabetes negligence claim, the solicitor will be entitled to a success fee deducted from your compensation award (capped at 25%).
    • If your case is unsuccessful and you do not receive compensation, you do not have to pay them any legal fees.

    This service removes the financial risk of starting a claim, allowing you to pursue compensation regardless of your financial situation.

    Diabetes Misdiagnosis FAQs

    There are three main types of diabetes, each with different causes, symptoms, and treatment needs:

    Type 1 diabetes

    Type 1 diabetes typically develops during childhood or adolescence. It occurs when the body’s immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas.

    People with type 1 diabetes must take daily insulin, either through injections or an insulin pump, to manage their blood sugar levels and maintain their health.

    Type 2 diabetes

    Type 2 is the most common type of diabetes and usually develops in adulthood, although it can occur at any age. It is often associated with lifestyle factors such as poor diet, lack of physical activity, and obesity.

    In type 2 diabetes, the body becomes resistant to insulin, causing blood sugar levels to rise. Management typically involves lifestyle changes, oral medications or insulin therapy.

    Gestational diabetes

    Gestational diabetes can develop between the 24th and 28th week of pregnancy when the hormones produced by the placenta interfere with the body’s ability to use insulin effectively.

    It requires careful monitoring and management to ensure the health and well-being of both the mother and the baby. In most cases, it resolves after delivery, but it does increase the risk of developing type 2 diabetes later in life.

    Pre-diabetes, also known as non-diabetic hyperglycaemia, is a condition where blood sugar levels are higher than normal but not yet high enough to be diagnosed as type 2 diabetes.

    It is an important early warning sign, as untreated pre-diabetes significantly increases the risk of developing type 2 diabetes and related complications.

    Common causes of pre-diabetes include:

    • Insulin resistance: The body’s cells become less responsive to insulin, causing blood sugar levels to rise.
    • Genetics and family history: A family history of diabetes increases your risk.
    • Lifestyle factors: Sedentary lifestyle, poor diet (high in processed foods and sugary drinks), and excess body weight are major contributors.

    Pre-diabetes often shows no symptoms, which is why regular screenings are recommended for individuals at risk. If you are diagnosed with the condition, this is an opportunity to make positive lifestyle changes to prevent or delay the progression to type 2 diabetes, such as:

    • Follow a balanced diet rich in fruits, vegetables, lean proteins, and healthy fats.
    • Engage in regular exercise such as walking and cycling to improve insulin sensitivity.
    • Achieve and maintain a healthy weight to lower blood sugar levels.
    • Schedule regular check-ups to monitor blood sugar and overall health.

    If your healthcare provider has failed to diagnose hyperglycaemia and your condition has progressed to type 2 diabetes, you might be entitled to make a diabetes medical negligence claim.

    Diabetes can be due to a combination of genetic, environmental, and lifestyle factors. The specific causes of diabetes can vary depending on the type of condition:

    • Type 1 diabetes: The immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. The exact cause is not fully understood, but it likely involves a combination of genetic predisposition and environmental triggers, such as viral infections.
    • Type 2 diabetes: It usually develops due to both genetic and lifestyle factors. The main risk factors include being overweight, unhealthy eating habits, a family history of diabetes, increased age and certain medical conditions.
    • Gestational diabetes: It is caused by hormonal changes that increase insulin resistance. It is more likely to occur in women who are overweight, have a family history of diabetes, or have previously had gestational diabetes.
    The symptoms of diabetes can vary depending on its type and the individual, but the most common ones include:

    • Frequent urination and increased thirst.
    • Unexplained weight loss despite an increased appetite.
    • Feeling tired because glucose cannot enter the cells to be used as energy.
    • Blurred vision and other vision problems.
    • Slow healing of wounds, causing minor cuts and sores to take longer to heal than usual.
    • Increased susceptibility to infections, such as urinary tract, yeast, and skin infections.
    • Tingling or numbness, especially in the hands and feet.
    Diabetes is diagnosed through a combination of medical history, physical examination, and various blood tests. Early and accurate diagnosis is essential to prevent serious complications, including nerve damage, kidney disease, heart problems and vision loss.

    The diagnostic process may include the following steps:

    Medical history

    This plays an essential role in diagnosing diabetes. Your healthcare provider will assess your risk factors by asking you about:

    • Symptoms such as frequent urination, excessive thirst, unexplained weight loss or fatigue.
    • Whether any family members have been diagnosed with diabetes.
    • Medical conditions, such as high blood pressure, kidney disease or obesity.
    • Medications and lifestyle factors, such as diet, physical activity and smoking habits.

    This information, along with further testing, will help doctors make an accurate diagnosis and decide the appropriate treatment plan. It is essential to provide thorough and accurate information during the medical history assessment to ensure a comprehensive evaluation.

    Physical examination

    A physical examination is necessary for diagnosing diabetes. During a physical exam, your doctor may:

    • Measure your weight, height and body mass index (BMI), as obesity is a significant risk factor.
    • Check your blood pressure, which is often elevated in people with diabetes.
    • Examine your skin for infections or darkened patches (acanthosis nigricans) linked to insulin resistance.
    • Assess your eyes for signs of diabetic retinopathy.
    • Examine your feet and legs for poor circulation, nerve damage or foot ulcers.

    While a physical exam alone cannot confirm diabetes, it provides valuable insight into your overall health and possible complications.

    Blood tests

    Blood tests are essential to confirm a diabetes diagnosis. Common diagnostic tests include:

    • The Fasting Plasma Glucose (FPG) test measures your blood sugar level after fasting for at least 8 hours. A result of 126mg/dL or higher on two separate occasions indicates diabetes.
    • The Oral Glucose Tolerance Test (OGTT) involves drinking a sugary solution, followed by blood sugar measurements at different intervals. A blood sugar level of 200 mg/dL or higher after two hours indicates diabetes.
    • The Haemoglobin A1c (HbA1c) test provides an average of your blood sugar levels over the past two to three months. An HbA1c level of 6.5% or higher indicates diabetes.

    Random blood sugar test

    If you have severe symptoms of diabetes, a random blood sugar test may be done at any time. A blood sugar level of 200 mg/dL or higher, along with other symptoms, may suggest diabetes.

    If your healthcare provider has failed to give you a correct diagnosis and this has caused you pain and suffering, a solicitor can help you claim compensation.

    If you have been diagnosed with diabetes, you will typically need to make some lifestyle changes, take medication and have regular checks, including blood tests. The specific approach may include:

    • Maintaining a balanced and nutritious diet.
    • Engaging in regular exercise to lower blood sugar levels and maintain a healthy weight.
    • Regularly checking blood sugar levels using a blood glucose meter to understand how your body responds to different foods, activities, and medications.
    • Oral medications or insulin injections to help regulate blood sugar levels.
    • Ongoing monitoring and regular medical visits.

    Diabetes management is a lifelong commitment, and it is essential to work closely with your doctor to develop a personalised treatment plan that suits your needs. By actively managing your condition, you can reduce the risk of complications and maintain a good quality of life.

    Diagnosing diabetes as early as possible is essential to start a treatment plan and prevent severe side effects. A delayed diagnosis can be life-threatening and lead to complications such as:

    • Heart attack and stroke – Consistently high blood sugar levels can damage the blood vessels and increase the risk of coronary artery disease, a heart attack or stroke.
    • Nerve damage – Elevated blood sugar levels over a prolonged period can damage the nerves throughout the body, mainly affecting the arms and legs.
    • Amputations – Amputations are a potential complication of diabetes, particularly when the condition is not well managed and gives rise to peripheral arterial disease (PAD) and diabetic neuropathy.
    • Kidney disease and failure – High blood sugar levels can damage the blood vessels in the kidneys and lead to kidney failure, which requires dialysis or a kidney transplant.
    • Blindness – Diabetes can also damage the blood vessels in the retina, causing it to swell and impair its ability to transmit clear visual signals to the brain.
    • Peripheral arterial disease (PAD) – It is a common complication of diabetes that occurs when there is a build-up of fatty deposits and plaque in the arteries in the legs and feet.
    • Miscarriage and stillbirth – Uncontrolled high blood sugar levels in pregnant women with diabetes can negatively impact the health of the developing foetus.

    If you have developed any of the above or other complications due to the misdiagnosis of diabetes, you might be entitled to start a compensation claim.

    A wrongful diagnosis of diabetes occurs when a healthcare professional incorrectly tells you that you have diabetes when you do not. This can have serious consequences, leading to unnecessary treatment, lifestyle restrictions and emotional distress, as well as financial losses.

    Some possible scenarios that can contribute to a wrongful diagnosis of diabetes include the following:

    • Inaccurate laboratory tests – Diagnostic tests may be incorrectly interpreted or temporarily affected by factors such as illness, medication or stress.
    • Misinterpretation of symptoms – Failing to investigate common symptoms like excessive thirst, frequent urination or fatigue can result in a wrongful diagnosis.
    • Diagnostic errors – Factors such as medical history, family history, lifestyle factors, and physical examination findings should all be considered for an accurate diagnosis.
    • Insufficient follow-up testing – Diabetes diagnosis often requires multiple tests over time to confirm the presence of the condition. If follow-up testing is inadequate or omitted, it can lead to a false diagnosis.

    If you believe you have been wrongly diagnosed with diabetes, it is important to seek a second medical opinion to confirm or reassess the diagnosis. If you were misdiagnosed and this has caused avoidable harm, you could be eligible for compensation.

    Yes. As a parent or legal guardian, you can make a diabetes claim for your child if they were misdiagnosed. A false diabetes diagnosis in a child can have significant consequences for their health and well-being, and seeking compensation can help address the emotional and financial impact of the medical negligence.

    To start a claim on behalf of your child, you must apply to the court to be appointed as their litigation friend. They will determine your eligibility by verifying whether you have a conflict of interest with the child and that you can conduct legal proceedings fairly and competently.

    If you manage to secure compensation for your child, this must be approved by a judge during an Infant Approval Hearing. The settlement will typically be kept in a court bank account or a personal injury trust and released to the child when they turn 18.

    If you believe you may have a valid diabetes misdiagnosis claim, use our online claim form or call 0800 470 0474 today to speak to a legal adviser. They can let you know whether you are eligible for a no win no fee service and answer any questions you might have.
