When an alcoholic doesn’t eat, it can be a sign of a serious health issue. Alcoholism can lead to malnutrition, as it can interfere with the body’s ability to absorb nutrients. It can also damage the digestive system and cause a loss of appetite. If you or someone you know is struggling with alcoholism and is experiencing a lack of appetite or difficulty eating, it is important to seek medical attention and support from a healthcare professional. A doctor or nutritionist can help create a plan to address the nutritional needs and address any underlying health concerns.
