Alkali disease, also known as milk-alkali syndrome or calcium-alkali syndrome, is a rare medical condition caused by excessive intake of calcium and alkali compounds. Symptoms of the condition may include nausea, vomiting, abdominal pain, and headaches. There are several synonyms for the term 'alkali disease' that are commonly used in the medical industry. These include metabolic alkalosis, milk-alkali poisoning, and hypercalcemia. Treatment for the condition typically involves discontinuing the intake of alkali-rich foods and medications, and replenishing fluid levels. If the condition persists, additional medical intervention may be necessary to address the underlying causes.
