Diabetes and Appetite

Diabetes is a medical condition characterized by high blood glucose levels resulting from the body's inability to use or produce insulin properly. It is associated with various symptoms, including appetite changes. Although heightened hunger (polyphagia) is often linked with diabetes, there are instances where a diabetic person may experience a loss of appetite, proving that the relationship between diabetes and appetite isn't always straightforward.

Type 1 and Type 2 Diabetes: An Overview
Type 1 diabetes, also referred to as juvenile diabetes, is an autoimmune condition where the body destroys its insulin-producing cells, usually leading to an increase in appetite because the body struggles to get energy from food. With Type 2 diabetes, the body becomes resistant to insulin or doesn't produce enough insulin. This form of diabetes is often associated with being overweight, rare are the cases where it leads to a loss of appetite.

Can Diabetes Cause Loss of Appetite?
The short answer is yes, diabetes can cause a loss of appetite, but it's not a typical symptom. Diabetes itself often causes increased hunger. However, loss of appetite can occur when complications or issues linked to diabetes arise. When the body is in a state of prolonged high blood sugar levels, a condition known as hyperglycemia, it can lead to decreased appetite. Other emotional and physical stressors, such as depression or gastroparesis (delayed stomach emptying), often seen in people with diabetes, can also lead to appetite loss.

Diabetes and Medication
Another facet to consider is the effect of medication on one's appetite. Certain diabetes medications like Metformin commonly result in gastrointestinal side effects, including nausea and a decrease in appetite, especially when the patient first starts taking them. Understanding this can help patients and caretakers properly manage the situation.

Importance of Managing Blood Glucose Levels
The key to managing both diabetes and appetite changes is to maintain stable blood sugar levels. Regularly monitoring your blood glucose levels, along with a balanced diet and regular exercise, forms the cornerstone of diabetes management. It's important to communicate any significant changes in appetite to your healthcare team as it may indicate uncontrolled blood sugar levels or an emerging complication requiring immediate attention.


While diabetes typically increases appetite, several factors, including diabetes complications, stress, and medication, can trigger a loss of appetite in some people with diabetes. Careful monitoring and management of blood sugar levels, regular consultations with your healthcare provider, and adhering to prescribed medication can help navigate these potential changes. As with any health condition, it's crucial to pay attention to your body and communicate openly with your healthcare team to ensure optimal management of your diabetes.
