An appetite stimulant is a substance or medication that increases a person’s desire to eat. These stimulants are commonly used to help individuals who have a reduced appetite due to medical conditions, treatments such as chemotherapy, or other factors. Appetite stimulants work by acting on the appetite-regulating centers in the brain or by increasing the release of certain hormones involved in hunger and satiety. They can help improve food intake, promote weight gain, and prevent malnutrition in individuals who have difficulty eating enough to meet their nutritional needs. However, it’s important to use appetite stimulants under the guidance of a healthcare professional to ensure they are safe and effective for the specific situation.
