Facial edema may be due to cirrhosis, allergic reaction, glomerulonephritis, primary aldosteronism, heart failure, etc. It is necessary to take furosemide, loratadine and other drugs for the cause. 1. Cirrhosis: Liver insufficiency leads to insufficient albumin synthesis, plasma colloid osmolality decreases, and water leaks out into the tissue space and causes facial edema. You can take antiviral drugs such as entecavir and tenofovir, and diuretics such as spironolactone and furosemide. 2. Allergic reaction: Facial contact with pollen, dander, seafood and other allergens induces an allergic reaction, resulting in facial edema. You can take chlorpheniramine maleate, loratadine, benadryl and other anti-allergy drugs for treatment. 3. Glomerulonephritis: due to the glomerular local immune material deposition leads to glomerular filtration rate decrease, water, sodium retention and facial edema, you can take prednisone, cyclophosphamide and other drugs to inhibit immune reaction. 4. Primary aldosteronism: excessive secretion of aldosterone synthesis in the adrenal cortex leads to water and sodium retention and facial edema. You can take spironolactone, aminopterin, eplerenone and other aldosterone antagonists for treatment. 5. Heart failure: due to the decline of the right heart function, the right ventricle blood stagnation, resulting in systemic venous return obstacles, and thus facial edema, you can eat furosemide, spironolactone and other diuretics, digoxin, cediran and other cardiac drugs and nitroglycerin and other vasodilators. Facial edema may also be other diseases, should be timely medical treatment, pay attention to the physician under the guidance of medication.
