A low blood pressure of 60 to 90 mmHg can be improved by diet or treated with medication. If the blood pressure has been maintained at 60 to 90mmHg without any symptoms, it may be related to the individual’s physique and does not require special treatment or deliberate supplementation. If the usual blood pressure is 120mmHg and suddenly drops to a blood pressure of 60mmHg to 90mmHg, if there are no obvious symptoms such as dizziness and generalized weakness, you can eat more food with high nutritional value, such as eggs, lean meat, milk, etc., and strengthen physical exercise. If the blood pressure is 60-90mmHg and some obvious discomfort occurs, it can be regulated by medication under the guidance of a doctor, such as fludrocortisone, octreotide, midodrine, etc. Low blood pressure should be promptly consulted and properly treated under the guidance of a doctor.
