What happens with low blood pressure?

Low blood pressure refers to a systolic pressure below 90 mmHg and a diastolic pressure below 60 mmHg. In such cases, symptoms such as blurred vision, dizziness, palpitations, reduced urine output, shock, or fainting may generally occur. Patients should promptly seek treatment at a正规 medical facility. The specific analysis is as follows:

1. Blurred Vision

This is usually temporary and mostly caused by changes in body position, such as suddenly standing up after prolonged squatting. At this time, the significant change in blood pressure makes patients prone to experiencing blurred vision, sometimes accompanied by dizziness. Patients can take medications such as acarbose tablets or droxidopa capsules under a doctor's guidance to improve symptoms.

2. Dizziness

In some patients, persistently low blood pressure leads to insufficient blood supply and inadequate nutrient delivery to vital organs such as the brain, heart, and kidneys. When cerebral perfusion is insufficient, dizziness occurs. Immediate intervention to raise blood pressure is required. Patients should follow medical advice to take medications for elevating blood pressure and relieving dizziness. Commonly used drugs include midodrine hydrochloride tablets and Yangxue Qingnao granules.

3. Palpitations

Due to decreased peripheral blood pressure, venous return is insufficient, resulting in inadequate cardiac blood supply and impaired normal heart function, leading to palpitations or feelings of anxiety. Severe cases may cause insufficient peripheral blood flow, resulting in cold limbs and cold sweats. In such situations, patients can take medications such as Wenxin Granules or Shengmai Oral Liquid under medical supervision to alleviate discomfort.

4. Reduced Urine Output

When blood pressure drops, blood flow through the kidneys significantly decreases, leading to reduced urine output. If low blood pressure is due to constitutional factors, dietary adjustments can help—drinking more lightly salted water or consuming salty foods, and increasing fluid intake to boost blood volume.

5. Shock or Fainting

If blood pressure drops too rapidly and systolic pressure falls below 70 mmHg, fainting or even shock may occur. In such cases, emergency services (e.g., dialing 120) should be called immediately, and first aid measures must be taken promptly.

In summary, when symptoms of low blood pressure appear, it is recommended to seek timely medical attention at a正规 hospital and select appropriate medications based on actual symptoms to improve the condition.
