Low pressure is diastolic pressure, and if it is currently 48mmHg, this is not normal and the patient is likely to experience dizziness, weakness, panic, palpitations and other uncomfortable symptoms. The standard diastolic blood pressure range should be 60-80mmHg. Patients who suddenly have a lower diastolic blood pressure may be due to an overdose of antihypertensive drugs or currently in a cachectic state, and recent frequent nausea, vomiting and diarrhea may cause a lower diastolic blood pressure. Patients are advised to first elevate their blood pressure, for example, they can take oral raw vein drink, or they can also elevate their blood pressure in combination with sedative ginseng injection and, if necessary, sedative dopamine. In addition, it is important to further identify the cause of hypotension and treat the primary disease to help prevent the reoccurrence of hypotension.
