What is Asthenia?

Asthenia is a medical term for an overwhelming feeling of weakness or lack of energy. It's not just ordinary fatigue; it can significantly impact daily activities. This condition can stem from various sources, including chronic illness, mental health issues, or lifestyle factors. Intrigued by how asthenia might be affecting you or someone you love? Let's examine its causes and treatments together.

Asthenia is a term used to describe a lack of energy, strength or a general feeling of weakness. It can also refer to feeling tired all the time and muscle fatigue. Several conditions may contribute to the disorder, including cancer, chronic fatigue syndrome and anemia. Some forms of the condition are linked to immune system disorders that prevent muscles from operating normally.

Myasthenia gravis is a form of asthenia that disrupts the signal sent by nerves that control muscle contraction. In this form of asthenia, the immune system produces too many antibodies that block nerve impulses from reaching the muscles. Weakness can occur in the face, limbs, neck or in the muscles that control breathing.

Chronic fatigue syndrome may contribute to asthenia in some patients.

The first sign of this disease is commonly seen in the eye muscles and may affect the eyelid or muscles that control vision. In some patients, slurred speech or trouble swallowing might be a sign of the disorder. For others, weakness in the legs that causes an uneven gait might appear. The symptoms commonly vary from one person to another in how they appear and in their severity.

Asthenia can cause a disorder of the thymus gland.

Diagnoses of the various forms of asthenia often take years, especially if the symptoms are mild, because the signs may mimic other diseases. A blood test can detect high levels of certain antibodies that spark the disorder when the eye is affected. In other tests, a substance can be injected into the patient that causes muscle weakness to temporarily resolve. Some doctors use a device in the diagnosis process to stimulate nerves and muscles to measure if they react normally. Asthenia can afflict both genders at any age, but is more common in children.

Pregnant women with the condition can pass it on to an unborn child. The mother’s antibodies might attack the fetus, which then becomes paralyzed and unable to move in the womb. After birth, the baby may suffer limited motion of the joints, often in several joints. There is no cure for this kind of asthenia but it can be prevented if the mother is treated with medication that limits the production of antibodies while she is pregnant.

Individuals suffering from asthenia may experience an overall feeling of weakness.

Asthenia due to autoimmune system disorders can be controlled with immunosuppressive medications that block the overproduction of antibodies and improve muscle strength. In some patients, a disorder of the thymus gland contributes to weakness, and its removal might help. Sometimes, donor blood is used to flush abnormal antibodies from the blood as well.

@Jacques6 - There are supposed to be over 450 diseases that cause weakness -- no wonder it takes doctors years to figure out if their patients have asthenia or not.

Something as simple as diarrhea can cause muscle weakness, but diseases like progressive muscular atrophy can too. The symptoms are all fairly common too, other than eye bulging.

I've thought that I might have it several times, but my doctor can't figure out if I do. So far, he thinks that I have anemia and sit in front of a computer screen enough to blur my vision. I trust my doctor, so I have been taking more vitamins.

Anemia is probably the easiest cause of asthenia to avoid. Menstruating women need to make sure to take their vitamins -- especially calcium and iron. A single daily vitamin everyday can greatly reduce your chance of becoming anemic, which in turn helps with asthenia.

The problem with anema is that it can creep up on you – the average diet lacks a lot vitamins and minerals. Men and women need to eat more leafy greens -- I know that it's cliche, but it's true. I eat at least one salad a day and try to have vegetables with dinner -- even if it's pizza.
