Dehydration could potentially lead to an increase in blood sugar levels.
In the world of diabetes management, hydration plays a crucial role that is often overlooked. Dehydration, a condition characterized by the loss of too much water from the body, can significantly impact blood sugar levels.
Dehydration raises blood sugar levels in people with diabetes. This happens as dehydration concentrates glucose in the blood, reducing insulin effectiveness, and triggering the release of stress hormones such as cortisol. When dehydrated, there is less water in the bloodstream, so the same amount of glucose is confined to a smaller volume, leading to higher measured blood sugar.
Moreover, dehydration impairs insulin sensitivity, meaning glucose is less efficiently transported into cells, causing it to remain in the blood longer. Dehydration also triggers the release of stress hormones such as cortisol, which stimulate the liver to produce more glucose, further increasing blood sugar levels. Reduced kidney function during dehydration impairs glucose clearance, compounding the problem.
For people with type 1 diabetes, the risk of dehydration during exercise can be higher due to fluid losses from sweat and increased urine output. This is why maintaining adequate hydration is critical for effective blood sugar management and to avoid falsely elevated readings or worsened glucose control.
If left untreated, hyperglycemia (high blood sugar levels) can lead to a potentially life-threatening condition known as diabetic ketoacidosis (DKA). Symptoms of DKA include shortness of breath, fruity-smelling breath, nausea and vomiting, and a very dry mouth.
To manage blood sugar levels, a person can adopt a nutritious diet, maintain a moderate weight, get regular physical exercise, drink enough water, monitor blood sugar levels, eat meals at regular times, and limit alcoholic drinks. A nutritious diet should contain plenty of fruit and vegetables, be lower in calories, saturated fat, trans fat, sugar, and salt, and water should be drunk instead of fruit juice or soda.
Common causes of excessive water loss from the gastrointestinal tract include vomiting, diarrhea, fistulas, and using laxatives. Other medical conditions that cause water loss in the body include pancreatitis, peritonitis, sepsis, severe hyperthyroidism, asthma, and chronic obstructive pulmonary disease.
Symptoms of dehydration include feeling thirsty, dry skin and lips, fatigue, dark urine, decreased urine output, headaches, muscle cramps, lightheadedness, dizziness, and fainting. Common causes of failure to replace water loss include immobility or an impaired thirst mechanism. Common causes of excess water loss from the kidneys include medications such as diuretics, acute and chronic kidney disease, and post-obstructive diuresis.
In summary, maintaining adequate hydration is essential for managing blood sugar levels, particularly for people with diabetes. Dehydration can lead to hyperglycemia by decreasing the amount of water in a person's bloodstream, causing a higher concentration of blood sugar. Therefore, it is crucial to stay hydrated, especially during physical activity, to avoid dehydration and its potential impact on blood sugar control.

- Dehydration also impairs insulin sensitivity, making it difficult for glucose to be efficiently transported into cells, causing it to remain in the blood for longer periods.
- Reducing kidney function during dehydration further impairs glucose clearance, exacerbating the issue of high blood sugar levels.
