Damage to the internal organs in dry syndrome may result in hypokalemic muscle paralysis, nausea, dyspepsia, and a dry cough. 1. Hypokalemic muscle paralysis: Patients with renal damage lead to type I renal tubular acidosis, resulting in hypokalemic muscle paralysis. Severe cases may present with kidney stones, renal insufficiency and calcification of the kidneys. 2. Nausea and dyspepsia: if the patient has liver damage, nausea, jaundice, discomfort in the liver area and other symptoms may occur, which may lead to liver cirrhosis and intrahepatic bile duct stones. 3. Dry cough: when patients combine with interstitial pneumonia, there are no respiratory symptoms in the early stage. However, in the later stage, patients will have dry cough, shortness of breath and dyspnea. It is recommended that patients with dry syndrome go to the hospital in time to fully identify the condition and standardize the treatment under the guidance of the doctor. Do not delay to avoid danger.
