Can a cold cause high blood pressure?

Although a cold is not a serious illness, it may cause some complications if you are not careful, such as pharyngitis, viral myocarditis, nephritis, pneumonia, otitis media and other diseases. Many patients with hypertension ask if a cold will cause high blood pressure? A cold will cause changes in blood pressure, but as the cold improves, blood pressure will return to normal. A cold will not cause high blood pressure, so don't worry too much.

A cold is an upper respiratory tract infection caused by a virus. It is divided into two types: influenza and common cold. Influenza is caused by influenza virus, and common cold is caused by other viruses. The disease can occur at any season throughout the year, and the pathogens affected vary depending on the person's constitution.

Colds do not cause high blood pressure. The following factors can cause high blood pressure:

1. Changes in cardiac output: Cardiac output often increases in the early stages of hypertension.

2. Abnormal kidney and renal function: can cause water and sodium retention and increase blood volume, causing high blood pressure.

3. Lesions of the renin-angiotensin-aldosterone system:

RAAS is an important endocrine system for the human body to regulate blood pressure. It is composed of a series of hormones and corresponding enzymes. Regulates the water and electrolyte balance, blood volume, vascular tension and blood pressure in the human body. Angiotensin I is produced under the regulation of renin, and angiotensin II (a powerful pressor substance) is produced under the action of ACE.

4. Abnormal cell membrane ion transport: increase in Na + ca2+.

5. Increased sympathetic nerve activity increases heart rate, strengthens cardiac contractility, and increases cardiac output.

6. Increased vascular tension and thickening of vascular walls: changes in vasodilatory substances (pressure-reducing substances in the body: prostaglandins, atrial peptides, calcitonin gene-related peptide, urinary natriuretic hormone, antihypertensive polypeptide, N0, etc.).

Changes in vasoconstrictor substances: thromboxane, endothelin

7. Abnormal receptor ratio.

8. Hyperinsulinemia.

Regarding the above introduction, everyone should be clear that a cold will not cause high blood pressure, so there is no need to worry. If you have high blood pressure and are worried that a cold may raise your blood pressure even higher, you can track your blood pressure. If you find that your blood pressure is occasionally unstable when you have a cold, you can temporarily take some antihypertensive drugs to relieve it. Once the cold is cured, your blood pressure will naturally return to normal.
