Some people experience dizziness and vomiting when standing up, while the symptoms can disappear after lying down, which is a manifestation of postural hypotension. Postural hypotension is a condition in which blood pressure is lowered by more than 15% compared to the basal blood pressure when standing or sitting, resulting in symptoms such as dizziness, headache, nausea, vomiting, sweating and pallor, while the symptoms can be relieved after lying down. Postural hypotension is mostly seen in the elderly and patients with vegetative nerve dysfunction, such as patients with Parkinson’s disease, multiple system atrophy, and menopausal syndrome. For such patients, attention should be paid to the slow movement when changing from lying to standing position, so that they can adapt to the change in blood pressure caused by the change in position, thus avoiding symptoms such as dizziness, nausea, vomiting, etc. At the same time, drugs such as glutathione and midodrine hydrochloride can be taken orally to regulate the plant nervous function.
