Rebuilding muscle after uncontrolled diabetes: the importance of management and exercise

A recent report highlights that muscle loss caused by poorly controlled diabetes may be reversible through proper blood sugar management, adequate nutrition, and strength training, offering hope to those affected.

A period of poorly controlled diabetes can leave lasting effects, including a drop in muscle mass. But the loss is not necessarily permanent, according to Indian Express, which reported on a 44-year-old who asked whether he could rebuild muscle after bringing his glucose levels back into range. Dr Vineeta Singh Tandon, a senior consultant in internal medicine at ISIC Multispeciality Hospital, told the publication that recovery is often possible, although it usually requires more than better blood sugar readings alone.

When glucose remains high for an extended period, the body may struggle to use it properly and begin drawing on muscle for energy instead. That can lead to weakness and visible loss of lean tissue, but Dr Tandon said the body can often start to recover once diabetes is better managed. The key, she explained, is combining stable sugar control with enough food, especially protein, and regular exercise rather than waiting for muscle to return on its own.

That approach is consistent with wider diabetes guidance. DiabetesTeam says muscle loss associated with diabetes can be reduced, and in some cases reversed, through resistance training, adequate protein and better glycaemic control. Medical News Today also advises people with diabetes who want to gain muscle to prioritise strength work, eat enough calories and protein, and monitor blood sugar carefully as exercise habits change.

Dr Tandon said resistance exercise such as weights, bands or bodyweight movements two or three times a week can help stimulate muscle growth, while walking and other aerobic activity can improve insulin sensitivity. She suggested that most adults trying to rebuild muscle may need about 1 to 1.2 grams of protein per kilogram of body weight each day, unless a doctor advises otherwise. Foods such as eggs, fish, chicken, paneer, lentils, soy and Greek yoghurt can help meet that target, though people with kidney disease should not raise protein intake without medical advice.

The bigger warning sign is ongoing loss despite improved glucose control. Dr Tandon said continued weight or muscle loss may point to another problem, such as under-eating, thyroid disease, vitamin deficiencies, digestive issues, medication effects or another illness. That is why experts stress that muscle health matters alongside blood sugar, not after it. Sleep, hydration and personalised advice from a doctor or dietitian can all shape recovery, particularly for people who have been unwell for a long time.
