What should I do if my legs and feet are swollen on a hot day?
Your feet are swollen in hot weather, which may be caused by many factors, but most of them are caused by functional factors. The specific reasons may be as follows: 1, body position factors:
Walking or standing for a long time, improper sitting posture, long legs drooping and sedentary will all lead to poor blood circulation of lower limbs, so reducing the assistance of muscle exercise to venous blood return will cause edema. Improper shoes can also cause edema. This edema will subside after rest. When the weather is hot, edema will get worse.
2. Climate factors:
When the weather is hot, most of the peripheral blood vessels of the human body dilate, which makes the capillaries congested, so the skin, subcutaneous tissue and soft tissue all show mild swelling, which is the reason why they swell with heat and contract with cold.
Three physical factors:
Female edema is also related to the role of estrogen in promoting the transfer of intravascular fluid to interstitial space. For women of childbearing age, edema can be seen in hands, breasts, buttocks, abdomen, lower limbs and other parts. Patients have the characteristics of poor posture adaptability, that is, fatigue and edema are aggravated after standing for a long time, and relieved after bed rest. This edema is related to the increase of renin activity in blood when standing upright, which leads to the increase of aldosterone. Therefore, edema can occur in drooping parts of the body, such as ankles, and edema can also occur in other parts when it is heavy. After rest at night, edema can be absorbed and disappeared.
Overweight or obese patients, especially women, are prone to functional edema of lower limbs, and obese people have increased subcutaneous adipose tissue, which can weaken the support of superficial veins, make them easy to expand and reduce extravascular pressure; After losing weight and increasing exercise, edema can be improved or disappeared.
3, local chronic injury:
I used to have a history of ankle sprain, which will leave scars on soft tissues. When the weather is hot, due to tissue swelling, it is easy to oppress blood vessels and aggravate local swelling. If necessary, check ECG, B-ultrasound, liver function, urine routine and thyroid function. If there is no obvious pathological or organic reason, it can be considered as functional edema. Treatment:
1, stay in bed when edema is obvious; There should also be a rest time at noon to help the recovery of edema.
2. Salt restriction: the daily salt should not exceed 5g; Reduce the amount of drinking water appropriately;
3. Wear elastic socks and properly raise the lower limbs at night;
4, functional exercise: do easy leg exercises every day, often do simple foot exercises, eliminate tension and promote blood circulation. After long-term activities of legs and feet, you should also rest and massage.
4, edema is obvious, can be given drug treatment: spironolactone 20mg plus dihydrogram urine plug.
12.5mg (half a tablet) twice a day. Dihydrograms can be taken for 3 days and stopped for 3 days. After the edema subsides, the drug can be stopped without obvious side effects, and it is effective in treating edema.
The causes of edema of lower limbs are pathological and functional.
