Introduction
Vomiting usually leads to alkalosis. During severe vomiting, the vomitus often contains large amounts of digestive fluid, namely gastric acid. Gastric acid is an acidic substance; its excessive loss from the body results in a decrease in hydrogen ions within the body, thereby causing metabolic alkalosis. Patients may present with clinical symptoms such as restlessness, tetany of the limbs, and hyperactive tendon reflexes.
Vomiting usually leads to alkalosis, primarily due to the loss of acidic substances from the body.
During severe vomiting, the vomit often contains large amounts of digestive fluids, particularly gastric acid. Gastric acid is an acidic substance; when it is excessively expelled from the body, it reduces hydrogen ion levels and decreases overall acidity in the body. This results in a relative excess of alkaline substances, leading to metabolic alkalosis. Patients may experience clinical symptoms such as restlessness, limb spasms, and hyperactive tendon reflexes.
It is recommended to promptly go to the hospital for relevant examinations, including arterial blood gas analysis and electrolyte tests, to assess the severity of the condition. Under medical guidance, antiemetic medications such as ondansetron hydrochloride tablets or aprepitant capsules can be taken during vomiting episodes to prevent worsening of symptoms. Adequate fluid intake should also be maintained during vomiting to prevent dehydration. If hand or foot spasms occur, treatment with 10% calcium gluconate injection may be administered under medical supervision to improve the condition.
