Why do I feel dizzy after having sex?

Sex life is really very important for men and women, because sex life is not only a way of life, but also a way to deepen the relationship between two people. However, some women say that they always feel inexplicably dizzy after sex, and even have to lie in bed for a long time before they can return to normal. This situation is usually caused by hypoglycemia and requires prompt treatment.

Hypoglycemia refers to a fasting blood glucose concentration in an adult below 2.8mmol/L. Hypoglycemia can be diagnosed in diabetic patients when their blood glucose level is ≤3.9 mmol/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.

Clinical manifestations

Hypoglycemia occurs in episodes, and the duration and frequency vary depending on the cause, and the symptoms are ever-changing. The clinical manifestations can be summarized into the following two aspects.

1. Manifestations of autonomic (sympathetic) nervous system overexcitation

When hypoglycemia occurs, the sympathetic nerves and adrenal medulla release adrenaline, norepinephrine, etc., and the clinical manifestations are sweating, hunger, palpitations, tremors, pale complexion, etc.

2. Manifestations of brain dysfunction

It is a series of manifestations of brain dysfunction when there is a lack of adequate glucose supply. The initial symptoms include inattention, slow thinking and speech, dizziness, drowsiness, restlessness, irritability, strange behavior, etc. In severe cases, convulsions, coma and even death may occur.
