Lack of Appetite: Four Typical Causes
Eating delicious foods can be one of the greatest pleasures in life, and a healthy appetite is a sign of positive wellbeing. People who develop a lack of appetite lose their desire to eat. They either experience complete disinterest, or the idea of eating makes them feel nauseous. While a number of factors may cause appetite loss, four in particular are worth noting.
1. Chronic Disease
Lack of appetite is a common symptom of a number of chronic diseases. These include liver disease, celiac disease, Crohn's disease, chronic obstructive pulmonary disease (COPD), dementia, HIV, hypothyroidism, gastroparesis, and kidney or heart failure. People with cancer of the ovaries, pancreas, colon, or stomach may also find their appetite lacking.
Nutritious snacks high in protein and calories help people with chronic illness or cancer maintain body weight while trying to recover. Eating small amounts several times throughout the day and supplementing with liquid protein drinks can be helpful. Supportive family members can keep favorite foods handy and record meals in a food diary for reference.
Hypothyroidism is most common in women from 35 to 65 years of age. It is a condition in which the thyroid produces too little thyroid hormone. It causes a range of symptoms, including lack of appetite, fatigue, constipation, dry skin, and brittle nails.
A simple blood test can determine whether people suffer from an inactive thyroid. Doctors usually prescribe synthetic T4 (levothyroxine sodium), in the form of a daily pill, to bring the thyroid hormone into the normal range.

Use of certain medications can affect the appetite. These include:
- Anabolic steroids
- Blood pressure medications
- Sleeping pills
Regardless if it is listed above, people who experience a lack of appetite in conjunction with starting a new medication should consult with their doctor for solutions, which may include changing the drug or dosage. People should not stop taking their medication without their doctor's approval.
A change in appetite is one of the most common signs of depression. For some people, depression increases appetite, and for others it leads to a lack of appetite. When people experience appetite loss along with symptoms like sadness, guilt, disinterest in activities, digestive issues, sleep problems, or nausea, they should consult with a medical doctor or mental health care professional.
A healthy diet may help ward off depression. According to research, a Mediterranean-style eating plan high in fruits vegetables, nuts, legumes, whole grains, and fatty fish can help lower risks for depression. Studies also show that deficiencies in vitamin B6, vitamin B12, and tryptophan can have a negative influence on mood.
While periods of appetite loss are normal, a persistent lack of appetite is not. It can be a symptom of chronic disease, cancer, hypothyroidism, depression or a reaction to a new medication. People should contact their health care provider if appetite loss is chronic or if they are shedding weight without trying.
