Diabetes in the summer

Il diabetes is a chronic disease that affects millions of people around the world. It is characterized by a high concentration of sugar (glucose) in the blood, due to insufficient production of insulin or resistance to the action of insulin by the cells of the body. Insulin is a hormone produced by the pancreas that regulates blood sugar levels, allowing cells to use glucose as an energy source.

There are several types of diabetes, such as type 1 diabetesil type 2 diabetes and the gestational diabetes. Type 1 diabetes is a form of autoimmune diabetes in which the immune system attacks and destroys the insulin-producing cells in the pancreas. Type 2 diabetes is the most common form of diabetes and occurs when the body does not use insulin efficiently or does not produce enough insulin. Gestational diabetes occurs during pregnancy and can lead to complications for both the mother and the baby.

Factors to consider

During the summer, there are some important factors for people with diabetes to consider:

  1. Hyperglycemia: High summer temperatures can affect blood sugar control. Hot weather can increase insulin sensitivity, which means your body may need less insulin than usual. On the other hand, sun exposure can change the speed of insulin absorption, leading to higher blood sugar. It is essential to monitor blood sugar levels carefully and adjust your treatment plan according to seasonal variations.
  2. Hydration: Heat and increased physical activity can lead to increased fluid loss through sweat. People with diabetes need to pay special attention to hydration to avoid dehydration and excessive blood sugar concentration. Drinking plenty of water and sugar-free drinks is essential to maintain fluid balance.
  3. Physical activity: During the summer, many people tend to increase physical activity, such as swimming, walking or playing sports outside. Regular exercise can help control your blood sugar, but it’s important to pay attention to the effects of physical activity on blood sugar and make any changes to your treatment plan in consultation with a doctor or diabetes educator.
  4. Diet: Eating habits can change during the summer, with a greater tendency to consume sugary foods and carbonated drinks. People with diabetes should continue to follow a balanced and controlled diet, avoid excess sugar and prefer fresh and light food.
  5. Sun protection: People with diabetes are more prone to skin problems, and sun exposure can increase the risk of sunburn or infection. It is important to protect the skin with the use of appropriate sunscreen and wear protective clothing during the hottest part of the day.


In conclusion, diabetes may require special attention during the summer season. It is essential to carefully monitor blood sugar levels, maintain adequate hydration, adapt physical activity and follow a balanced diet. If you have any doubts or concerns, it is always recommended to consult a healthcare professional who specializes in diabetes for support and proper management of the disease.

Careful diabetes control during the summer can help improve quality of life and prevent short- and long-term complications. With proper management and care, people with diabetes can fully enjoy summer activities and face the hot season with greater safety and peace of mind.
