Teenagers may feel dizzy when squatting and standing up due to anemia, cardiovascular and cerebrovascular diseases, and orthostatic hypotension. Here are the possible reasons:

1. Anemia

Many people suffer from anemia, even if they look strong and healthy. Some people have a poor physical condition and tend to have a partial diet, which can lead to anemia over time. Anemia patients often feel dizzy when squatting for a relatively long time. They should eat more iron-rich foods, such as red dates and peanuts, to improve their blood levels. Women should pay more attention to replenishing blood due to menstrual blood loss.

2. Cardiovascular and Cerebrovascular Diseases

Patients with cardiovascular and cerebrovascular diseases may experience dizziness when squatting due to poor blood circulation and brain hypoxia. This phenomenon is common in these patients. If it occurs frequently, they should seek timely medical treatment to prevent further deterioration.

3. Orthostatic Hypotension

Orthostatic hypotension occurs when most of the blood is concentrated in the lower body during squatting. When standing up, the blood may not redistribute quickly enough, leading to transient cerebral ischemia and hypoxia, which causes dizziness in teenagers. Monitoring the patient's blood pressure in different positions (lying, sitting, and standing) is necessary. Those with obvious symptoms may take Shengmaiyin for symptomatic treatment.
