Combat Fatigue and Loss of Appetite

What Causes Fatigue and Loss of Appetite

It can be difficult to determine the cause of fatigue and loss of appetite for a variety of reasons. One reason is that individuals who suffer from these problems often have other health problems that may mask the cause of fatigue. Both of these problems are consistent with conditions that cause continuous pain. Some of these conditions that could cause fatigue and no appetite include fibromyalgia, nerve damage, and migraines. Other causes could include pregnancy, chronic fatigue syndrome, premenstrual system (PMS), or alcohol withdrawal syndrome.



In addition to the conditions that can cause fatigue and a decreased appetite, there are some medications that can also cause these problems. One of the obvious ones are sleeping pills. While sleeping pills may help you sleep at night, they can also cause unwanted fatigue during the daytime hours.

Other medications that can cause fatigue and loss of appetite include prescriptions such as antibiotics, anabolic steroids, codeine, or morphine. While these medications are prescribed to help with a medical problem that you may be experiencing, they can make some people tired and feel like they do not want to eat.

Lastly, blood pressure medicine and diuretics have been known to cause fatigue and a decreased appetite in some people. It is important to remember that everybody is unique so medications will impact different people in different ways.



Even if an individual does not take any medications or have any pre-existing conditions that may be causing fatigue or no appetite, there could be a psychological cause. Probably the most common psychological cause of these problems is stress. Stress is unique for everyone which means that the cause of stress could come from a variety of places depending on the individual.

Other psychological conditions that can cause fatigue and decrease appetite include depression, anxiety, and grief. The duration of these conditions will, of course, vary depending on severity, external circumstances, and the person themselves.

Bulimia, anorexia, and bipolar depression have also been known to cause fatigue and decreased appetite. The psychological conditions listed here often make it difficult to determine the exact cause of fatigue and/or decreased appetite because often the person is also stressed and may be taking medications that can cause these symptoms as well.


Fatigue and Loss of Appetite: Children

Fatigue and decrease in appetite are particularly concerning in children because we like to see children full of energy and eating everything that we put in front of them. Some causes of these problems in children can be constipation, depression, anxiety, or intestinal worms. Other causes could include acute appendicitis, cancer, anemia, or lupus. These conditions need to be diagnosed by a physician to appropriately determine a plan of care to help the child feel better.

Not all causes of fatigue and decrease in appetite are as serious as the ones listed above. It could be as simple as the child is not sleeping well at night so they are fatigued throughout the day. Other reasons could include a slower growth rate than peers, coming off of antibiotics, or not getting a balanced diet.


Fatigue and Loss of Appetite: Older Adults

Getting older alone can cause fatigue and decrease appetite in some individuals. Other causes for these problems in older adults include depression, arthritis, cancer, neurological disorders, sleep disorders, and heart disease.


Fatigue and Loss of Appetite: When to Seek Help

It is time to seek help when fatigue and decreased appetite symptoms are impeding on an individual’s daily routines. Other reasons to seek help include if an individual is also experiencing dizziness, confusion, blurred vision, chest pain, shortness of breath, fainting, or an irregular/racing heartbeat.
