  • Obesity and Heart Conditions

    There are many factors that can cause heart conditions, which is part of the reason why heart conditions are so common. However, this also means that by controlling the various factors, it is possible to prevent the onset of heart conditions in adults.

    Obesity is one of the most common causes of heart conditions, especially coronary artery disease. Part of this is because there are more fatty elements in the blood of an obese person, hence increasing the risk of fatty deposits causing blockages in the coronary artery. This may result in a narrowing of the arteries and more strain on the heart.

    When there is a limitation of blood flow to the heart, ischaemia (a lack of oxygen to the heart cells) occurs. The cells of the heart may start to die due to lack of oxygen, resulting in a heart attack (myocardial infarction), which leads to heart muscle damage and heart muscle death.

    Obesity can also cause insulin resistance, which can result in diabetes, one of the major causes of heart conditions. Obesity can be caused by one or more of the following factors:

    • Genetic predisposition. Some people are more likely to become overweight or obese due to their genes
    • Overeating, or overeating foods that are high in calories
    • Lack of exercise.

    The first step in combating obesity is to expend more calories than consumed. This can be achieved through proper dieting and going on a regular exercise regimen. Low calorie meal replacement options are available to help you reduce calorie intake while avoiding hunger. At Gleneagles Hospital, our dieticians will assist you to craft personalised diet plans to suit your needs. Effective medical therapy are also available to help you lose weight without suffering from hunger. Gleneagles Hospital also has the expertise in performing bariatric surgery to help those with severe obesity achieve sustainable weight loss. Besides addressing the issue of obesity, overweight patients with hypertension, high cholesterol or diabetes should also undergo treatment for these conditions.

  • Diabetes and Heart Conditions


    Insulin is a chemical produced by the body to process sugar in the blood. When the body is resistant to insulin or there is an excess of sugar in the blood, the insulin may no longer be able to effectively process the sugar. High levels of glucose in the blood can damage artery walls, increasing the likelihood of deposits building up in the arteries and causing conditions such as:

    Diabetes can be managed through a combination of medication, weight loss treatment and lifestyle changes. Medical treatment for diabetes include insulin injections and medication that increase the patient’s production and absorption of insulin. Weight loss surgery can be performed on obese patients to help them manage their diet and lifestyle better. A change in diet and increase in exercise can help reduce the amount of glucose in their body, as well as lower the risk of suffering from heart conditions.

    At Gleneagles Hospital, we want to help you enjoy a high quality of living, even with diabetes. Our team of hormone specialists (endocrinologists) and allied health professionals can help you tailor personalised and effective treatment strategies with the aim to manage diabetes and prevent or slow the development of complications. We are also well-equipped to manage your diabetes in any medical circumstance, whether it is before or after surgery, pregnancy, or chemotherapy.

  • Thyroid Disorders and Heart Conditions

    While many common causes of obesity and diabetes are due to lifestyle, some people may have hormonal problems that can lead to obesity. These problems can be due to disorders with the thyroid, which is responsible for the production of hormones.


    Polycystic ovary syndrome in women and hypogonadism in men are 2 common thyroid disorders that can lead to obesity. Patients with these disorders can find themselves persistently gaining weight despite no changes in their lifestyle, and also difficulty in losing weight despite increased exercise. They may also experience mood swings and low energy levels, which can affect their diet and exercise.

    While these thyroid conditions cannot be cured, they can be managed on a long-term basis through medication and treatment. These treatments can help control or even reverse the symptoms of thyroid disorders, preventing the onset of obesitydiabetes and heart problems.
