If the elderly people have this kind of ankle swelling, first of all, we should rule out whether there is any correlation with the drugs they are currently taking. For example, some elderly patients take calcium channel blockers for a long time, which are commonly used antihypertensive drugs in the clinic, and the representative drugs include felodipine and nifedipine, etc. Long-term use may lead to ankle edema or even lower limb edema. For this situation, it is recommended that patients can take hydrochlorothiazide tablets and diphenhydramine drugs at the same time to help avoid ankle edema. If the edema does not improve, you can also switch to other types of antihypertensive drugs to lower blood pressure. There are also some patients who have ankle swelling, which may be due to heart failure or nephrotic syndrome or hypoalbuminemia, which may also be caused by these conditions. If it is caused by low albumin, it is recommended that albumin can be supplemented by intravenous means.
