Obesity with Type 2 Diabetes
Obesity and type 2 diabetes often occur together, as excess fat makes the body resist insulin. Losing weight, including through surgery, can dramatically improve or even reverse diabetes.
Causes & risk factors
- Excess body fat driving insulin resistance
- A diet high in sugar and refined carbohydrates
- Low physical activity
- Genetic and family history of diabetes
- Common in South Asians at a lower BMI
Common symptoms
- Passing urine often, especially at night
- Increased thirst
- Tiredness
- Blurred vision
- Weight changes
- Slow-healing cuts or frequent infections
Tests & diagnosis
Treatment & management
- Weight loss is central — even modest loss improves blood sugar
- A balanced, lower-sugar diet and regular activity
- Diabetes medicines, some of which also help weight
- Bariatric surgery, which often puts type 2 diabetes into remission
- Regular checks of eyes, kidneys, feet and heart risk
When to see a doctor urgently
- Diabetes that is hard to control despite treatment
- A high BMI with type 2 diabetes
- Symptoms of high sugar — thirst, frequent urination, blurred vision
- Interest in surgery to improve diabetes and weight
Frequently asked questions
Can weight-loss surgery cure diabetes?
Surgery does not guarantee a cure, but many people with type 2 diabetes see it go into remission after losing weight, sometimes coming off medicines. Ongoing follow-up is still needed.
How does losing weight help diabetes?
Less body fat, especially around the organs, makes the body respond to insulin better, lowering blood sugar. Even a 5-10% weight loss can make a real difference.
