Hello and welcome to e health forum.
The description of the history indicates the possibility of postural (orthostatic) hypotension, associated with autonomic neuropathy.
Autonomic neuropathy is a group of symptoms that occur when there is damage to the nerves âthat manage every day body functions such as blood pressure, heart rate, bowel and bladder âemptying, and digestion. In your case, probably the nerves controlling the blood vessels or the âheart may be affected, hence causing the symptoms you are having.
The causes for such conditions include advanced age, long term diabetes, heart failure, etc.â
Treatment is supportive and may need to be long-term. Several treatments may be attempted ââbefore a successful one is found. Various strategies may be used to reduce symptoms of light-ââheadedness or dizziness when standing, including - â
â1. Extra salt in the diet or taking salt tablets to increase fluid volume in blood vessels. â
â2. Fludrocortisone or similar medications to help your body retain salt and fluidâ
â3. Sleeping with the head raisedâ
â4. Wearing elastic stockingsâ.
5. Avoid prolonged standing â especially in hot, crowded places â and drink plenty of fluids. â
You may consult with your doctor for a physical examination and proper advice and treatment.
