Hypoglycemia Causes

The triggers that have been causing variations in hormone levels may affect the causes of hypoglycemia. However, we have covered some of the potential reasons for you below:

Hypoglycemia causes In People Without Diabetes

Blood Sugar Control - The hormone insulin, which is released by the pancreas, helps the body convert the carbohydrates (glucose) in food into energy. Unbalanced insulin secretion might originate from improper eating habits or bodily processes and lead to abrupt hypoglycemic episodes. Critical illnesses such as cancer, tumors, endocrine issues, insulinomas, etc. may sometimes cause hypoglycemic episodes. Know more about high blood sugar symptoms.

Hypoglycemia causes In People With Diabetes

People who have Type 2 diabetes take medication or administer insulin injections to control their insulin levels. Hypo- or hyperglycemia may result from an imbalance in insulin intake. It can also occur due to skipping a meal and/or increasing workouts without adjusting their meal plan. Drinking too much alcohol clogs your liver and prevents it from releasing the glucose that has been stored there into the circulation, causing hypoglycemia. Also know how to reverse prediabetes.

Causes Of Reactive Hypoglycemia

  • Possessing rare enzyme deficiencies, which can make it difficult for the stomach and intestines to break down food.
  • Having prediabetes, which can make it difficult for the pancreas to produce the right amount of insulin. Also know about prediabetes diet.
  • Having had stomach surgery, which can cause food to pass through the stomach and into the intestines too quickly.

Causes of Fasting Hypoglycemia

Several factors may contribute to fasting hypoglycemia:

  • medications such as sulfa medicines and aspirin
  • consumption of alcohol in excess
  • liver, kidney, heart, and pancreatic conditions
  • hormone levels that are too low
  • specific tumors

Hypoglycemia can be caused to a non-diabetic person due to numerous causes like drinking excess alcohol, infections, kidney problems, liver diseases, adrenal, and pituitary gland-related problems, etc. If the body produces excess insulin post a meal in a non-diabetic person then such a situation leads to a sudden reduction of blood sugar level causing hypoglycemia. This situation is called reactive hypoglycemia. Following a reactive hypoglycemia diet can easily treat the condition in one or two days.

Can dehydration cause hypoglycemia?

Dehydration can work in a reverse manner during the condition of hypoglycemia. In case you are dehydrated, then the glucose present in your blood is relatively more than the other fluids causing hyperglycemia which is higher sugar levels. However, drinking an ample amount of water daily can help to maintain blood sugar levels as water does not contain any calories.

The warning signs of hypoglycemia can be many. Of the many signs, the most common ones include dizziness, difficulty concentrating, looking pale, hunger, feeling weak, sweating, shakiness, irregular heartbeat, nausea, etc. If you notice any of these discussed signs, you can consult your doctor for a timely diagnosis and treatment.
