Why is my blood pressure low during menstruation?

Some female friends will experience symptoms of low blood pressure during menstruation, but some are due to physiological hypotension. If this is the case, there is no need to worry too much, just go to the hospital for regular check-ups. If it is pathological low blood pressure, it may be caused by certain diseases in your body. This situation mainly occurs in women with poor physical fitness.

1. Physiological hypotension

It refers to a group of healthy people whose blood pressure measurements have reached the standard for low blood pressure, but who have no subjective symptoms. After long-term follow-up, except for low blood pressure, there are no abnormalities such as ischemia and hypoxia in various systems and organs of the human body, and their life span is not affected.

2. Pathological hypotension

In addition to lowered blood pressure, it is often accompanied by symptoms of varying degrees and certain diseases.

(1) Primary hypotension refers to a state of low blood pressure without obvious cause, such as physiological hypotension (constitutional hypotension), which is more common in frail elderly people and women.

(2) Secondary hypotension refers to low blood pressure caused by a disease of a certain organ or system in the human body. This type of hypotension can occur rapidly in a short period of time, such as a sharp drop in blood pressure caused by massive bleeding, acute myocardial infarction, severe trauma, infection, allergies, etc. In most cases, hypotension occurs slowly and may gradually worsen, such as hypotension secondary to severe pulmonary tuberculosis, malignant tumors, malnutrition, cachexia, etc.

The diagnosis of hypotension is mainly based on whether the arterial blood pressure measurement reaches the hypotension standard. At the same time, paying attention to asking the following questions about patients with hypotension will help with diagnosis and differential diagnosis.

1. Inquire whether there are other vascular symptoms or other systemic diseases besides hypotension. If not, consider it as primary hypotension.

2. Ask whether there are any acute or severe illnesses that cause acute blood volume deficiency or acute cardiac function impairment or cardiac output dysfunction.

3. Ask whether the patient has any cardiovascular disease or peripheral vascular disease that may cause hypotension, and whether the patient has a history of living in high altitude areas. Whether there are any endocrine system diseases and clinical manifestations that may cause hypotension. Whether there are metabolic diseases or spinal cord lesions.

4. Ask when the hypotensive state occurred and whether there is any obvious relationship with the clinical symptoms and body position. Whether there is a history of long-term bed rest. Whether there is any cause of autonomic nerve damage due to surgery or trauma.

5. Ask about the duration of hypotension and the relationship between clinical manifestations and medications.

By asking about the above situations in detail, it can be determined whether the hypotension is primary or secondary, and whether it is acute hypotension. Combined with other clinical data, the primary cause can be determined.
