Dry mouth and bitter eyes, may be environmental high temperature, dry syndrome, diabetes, uremia, upper respiratory tract infection and other reasons.
1. Environmental high temperature: long-term in the hot and high temperature environment, the body sweating heat dissipation increase, water evaporation, resulting in the oral cavity, the eye surface water reduction, dry mouth and bitter eyes dryness.
2. Dry syndrome: autoimmune system dysfunction leads to the production of antibodies to attack the salivary glands, lacrimal glands and other glands, leading to saliva, tears and other synthetic secretion is insufficient, appearing in the dry mouth, bitter eyes dry.
3. Diabetes mellitus: when the blood sugar level exceeds the renal glucose threshold, the glucose level in the urine rises, leading to osmotic diuresis, and a large amount of water is lost through the urine, resulting in dry mouth, bitter eyes and dryness.
4. Uremia: antidiuretic hormone synthesis and secretion disorders or renal insensitivity to the action of antidiuretic hormone, renal urinary excretion increases, the body water loss and dry mouth and bitter eyes.
5. Upper respiratory tract infection: viral infection of the body induces the hypothalamus to elevate the body temperature regulation point, resulting in generalized hyperthermia, water evaporation increased, the eye surface, the mouth and other parts of the severe dehydration and dry mouth and bitter eyes dry asthma.
Dry mouth and bitter eyes, may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis, follow the doctor’s instructions for standardized treatment.
