The occurrence of low blood sugar symptoms during weight loss may be related to factors such as excessive dieting, unreasonable dietary structure, and excessive exercise. Hypoglycemia usually manifests as symptoms such as dizziness, palpitations, fatigue, and sweating, which can be alleviated by adjusting diet, eating regularly, and controlling exercise intensity. If the symptoms are repeated or aggravated, it is recommended to seek medical advice in time to troubleshoot diabetes, insulinoma and other diseases.

1. Excessive dieting
Long term severe calorie deficiency can lead to a lack of blood sugar sources. Especially when carbohydrates are strictly restricted, a lack of glucose supply in the body can easily lead to hypoglycemic reactions. It is recommended to consume no less than 150 grams of staple food per day. Low glycemic index foods such as oatmeal and whole wheat bread can be chosen to avoid prolonged fasting.
2. Imbalance in dietary structure
Insufficient intake of protein and dietary fiber can accelerate blood sugar fluctuations. During weight loss, it is important to ensure that each meal contains high-quality protein such as eggs and lean meat, paired with vegetables rich in dietary fiber such as broccoli and spinach. Moderate consumption of sugar free yogurt or nuts as an extra between meals.
3. Improper exercise schedule
Fasting exercise or prolonged exercise time can excessively consume blood sugar. It is recommended to supplement a small amount of carbohydrates, such as half a banana, one hour before exercise. Aerobic exercise should be controlled for 30-45 minutes to avoid high-intensity training in the morning without eating.

4. Pre diabetes
may be related to abnormal insulin secretion, often accompanied by polydipsia and polyuria. Diagnosis should be confirmed through oral glucose tolerance test, and medication such as acarbose tablets and glimepiride tablets can be used as prescribed to control blood glucose fluctuations.
5. insulinoma
is a rare cause characterized by severe hypoglycemia before meals, which can be detected by abdominal CT examination. After diagnosis, surgery is required to remove the tumor, and before surgery, injection of octreotide can be used to control symptoms.

During weight loss, it is important to maintain a regular diet of three meals a day, with a focus on complex carbohydrates such as brown rice and sweet potatoes as staple foods, paired with sufficient lean meat and green leafy vegetables. Pay attention to monitoring blood sugar changes before and after exercise, and carry candy with you for emergencies. If severe hypoglycemic reactions such as blurred consciousness occur, seek medical attention immediately. Long term weight control is recommended to consult a nutritionist to develop personalized plans and avoid extreme weight loss methods.
