There are many causes of puffy eyes, and the specific measures to be taken to eliminate puffy eyes need to be treated symptomatically according to the different causes. For puffy eyes caused by lack of sleep and excessive fatigue, it is usually necessary to pay attention to rest, get enough sleep, relieve fatigue, and apply hot compresses to the eyelids to promote blood circulation, so that the puffiness of the eyelids will gradually subside and be relieved. For eye swelling caused by exposure to certain irritating or allergic substances, the first step is to remove the irritating or allergic substance and give anti-allergy treatment or symptomatic treatment. For eye swelling caused by external forces, ice packs can be applied initially to reduce eye swelling, followed by hot packs at a later stage to promote the swelling of the eyelids to subside. If the swollen eyes are caused by kidney or heart disease, the original disease should be treated and dehydrating agents can be given to promote the elimination of swollen eyes according to the condition. In the case of puffy eyes caused by significant weight gain over a short period of time, treatment is also based on the specific cause. In the case of idiopathic edema, the swollen eyes do not require special treatment and can gradually subside on their own. In short, there are many causes of puffy eyes, so it is necessary to go to the hospital to identify the cause so that symptomatic treatment can be carried out.
