Overview, Causes, & Risk Factors
Malaise is a general feeling of physical discomfort or uneasiness.
stress
lack of sleep or sleep disorders
infections, such as acute bronchitis, a common cold, the flu, or infectious mononucleosis
a low blood count, called anemia
hormone imbalances, such as a low thyroid hormone level, called hypothyroidism. Another example is low adrenal hormone levels, called hypoadrenalism.
depression or other psychological disorders
autoimmune disorders, which are conditions in which a person's immune system attacks his or her own body for no apparent reason. Examples of autoimmune diseases include systemic lupus erythematosus and rheumatoid arthritis.
toxin or chemical exposure, such as carbon monoxide or lead poisoning
allergies
medications, such as antihistamines, cancer chemotherapy, or certain medications used to treat depression and high blood pressure. Examples include atenolol, paroxetine, and diphenhydramine.
systemic disorders, such as heart, liver, lung, or kidney disorders
uncontrolled diabetes
tumors or cancer, such as lung cancer or a blood cancer called leukemia
salt imbalances, such as a low sodium level or a high potassium level
chronic fatigue syndrome and fibromyalgia, two poorly understood conditions with no known cause. These conditions commonly cause malaise and make people feel weak and tired.
Other causes of malaise are also possible. Sometimes, the cause is unknown.
What is going on in the body?
Malaise is often the first sign of an infection or other disease. Many people can "feel" an infection or disease starting because they develop the feeling of malaise. The causes of malaise can range from working out or studying too hard to cancer.What are the causes and risks of the condition?
Almost any sudden illness and many chronic illnesses can cause malaise. The more common causes include:Other causes of malaise are also possible. Sometimes, the cause is unknown.
Symptoms & Signs
What are the signs and symptoms of the condition?
A healthcare provider may want to know several things when a person complains of malaise, such as:Other symptoms may be important in determining the cause of the malaise. For instance, the provider may want to know about fever, weight loss, or pain.
Diagnosis & Tests
How is the condition diagnosed?
The role of the healthcare provider is to help figure out the cause of malaise. This may be possible after a complete history and physical exam. In other cases, further tests must be done. This often involves blood tests, such as a complete blood count or CBC, which can help detect anemia or an infection. Blood hormone levels, such as thyroid function tests, can help diagnose hormone imbalances. Salt, or electrolyte, levels can also be checked with a chem-7 blood test. A blood glucose test can help detect diabetes.Other tests may be advised based on the suspected condition. For instance, a chest x-ray may be done if lung or heart disease is thought to be the cause. An x-ray test called a chest CT scan may be used if lung cancer is suspected.
Prevention & Expectations
What can be done to prevent the condition?
Prevention is related to the cause. Avoidance of stress and overexertion, getting enough sleep, and eating a healthy diet can prevent some cases of malaise. Taking medications as prescribed can prevent some cases due to diabetes and allergies.What are the long-term effects of the condition?
Malaise can limit a person's ability to work or go to school. Other long-term effects depend on the cause. For instance, cancer may result in death. An infection often goes away and results in no long-term effects.What are the risks to others?
Malaise itself is not contagious and poses no risk to others. However, malaise may be caused by an infection that is contagious.Treatment & Monitoring
What are the treatments for the condition?
In general, recommendations for treatment of malaise include:More specific treatment is directed at the cause. For instance, a person may need antibiotics for infection. Thyroid hormone medication may be needed for low thyroid levels. In other people, control of diabetes or another systemic disorder may be needed. Those with depression often need medication to treat their condition. Those with cancer may need surgery, chemotherapy, or radiation therapy.
What are the side effects of the treatments?
Side effects depend on the treatments used. Medication side effects can include allergic reactions, stomach upset, and headache. Surgery carries a risk of bleeding, infection, and allergic reaction to the anesthesia.What happens after treatment for the condition?
If the malaise goes away, a person may or may not need further treatment. For instance, an individual with diabetes needs lifelong treatment. Someone who was "overdoing it" may need no further treatment once he or she gets some rest. Someone with cancer may die if treatment is not successful.How is the condition monitored?
A person can often monitor his or her symptoms at home. Any new or worsening symptoms should be reported to the healthcare provider. Other monitoring is related to the cause. For instance, someone with diabetes needs to monitor blood sugars regularly.Attribution
