The causes of bitter mouth include environmental dryness, dry syndrome, diabetes, reflux esophagitis and other causes, and the treatments include applying methotrexate, metformin and other medicines for the causes.
1. Environmental dryness: prolonged exposure to high temperatures in dry environments, poor air circulation, water evaporation through sweat, in addition to drinking too little water and food too salty and other factors can lead to dehydration and bitterness in the body. This situation can be relieved by increasing the amount of drinking water, avoiding over-salted food, living environment ventilation and other measures.
2. Dry syndrome: the salivary glands are attacked by autoimmune disease, resulting in a decrease in the synthesis of body fluids, so the mouth is bitter. Hydroxychloroquine, methotrexate, cyclophosphamide and cyclosporine can be applied to inhibit the immune response, and drugs such as Hirsutine can be applied to stimulate the secretion of salivary glands.
3. Diabetes mellitus: renal osmotic diuresis leads to excessive urine synthesis and discharge, the body lacks water and bitter mouth. It can be treated by moderate exercise, diabetic diet, taking hypoglycemic drugs such as metformin, glimepiride, saxagliptin, or subcutaneous injection of insulin.
4. Reflux esophagitis: esophageal barrier sphincter dysfunction leads to acid reflux into the mouth, so it will be bitter. You can take eplazole, ranitidine, domperidone, aluminum magnesium carbonate and other drugs for treatment.
Pay attention to the use of medication under the guidance of a physician.
