What is the reason for shaking hands and weak legs?

Blood sugar concentration is a major health indicator of the human body. If the blood sugar concentration exceeds the normal value, it means hyperglycemia. If the blood sugar concentration is lower than the normal value, it means hypoglycemia. Many people in our lives are prone to hypoglycemia, and patients with hypoglycemia are afraid of hunger. Once they don’t eat, they may feel uncomfortable. So the question is, what is the reason for trembling hands and weak legs? Is it low blood sugar?

Hypoglycemia refers to a fasting blood glucose concentration in an adult below 2.8mmol/L. Hypoglycemia can be diagnosed when the blood glucose level of diabetic patients is ≤3.9mmol/L. Hypoglycemia is a syndrome caused by a variety of etiologies, characterized by low venous plasma glucose (blood sugar) concentration, and clinically by sympathetic nerve excitement and brain cell hypoxia. Symptoms of hypoglycemia usually include sweating, hunger, palpitations, tremors, pale complexion, etc. In severe cases, patients may also experience inattention, restlessness, irritability, and even coma.

Causes

Clinically, repeated occurrence of fasting hypoglycemia indicates an organic disease; reactive hypoglycemia caused by meals is more common in functional diseases.

1. Fasting hypoglycemia

(1) Excessive endogenous insulin secretion: Common causes include insulinoma, autoimmune hypoglycemia, etc.

(2) Drug-related: such as injection of insulin, sulfonylurea hypoglycemic drugs, salicylic acid, drinking, etc.

(3) Serious illnesses: such as liver failure, heart failure, kidney failure, malnutrition, etc.

(4) Deficiency of insulin antagonist hormones: such as deficiency of glucagon, growth hormone, cortisol, etc.

(5) Extrapancreatic tumors.

2. Postprandial (reactive) hypoglycemia

(1) Congenital deficiency of carbohydrate metabolizing enzymes: such as hereditary fructose intolerance.

(2) Idiopathic reactive hypoglycemia.

(3) Trophic hypoglycemia (including dumping syndrome).

(4) Functional hypoglycemia.

(5) Postprandial hypoglycemia in the early stages of type 2 diabetes.
