5 Possible Causes of Muscle Weakness in Arms (And What to Do About Them)

If you experience muscle weakness in your arms, it could be caused by a variety of different issues, ranging from everyday ailments to potentially life-threatening conditions. Fortunately, most cases of arm muscle weakness are not serious and can be easily treated with self-care methods such as rest and relaxation or at-home exercise. 

Here are five possible causes of muscle weakness in arms that you should know about.

5 Possible Causes of Muscle Weakness in Arms

1) Neuromuscular Disorders

Neuromuscular Disorders

A neuromuscular disorder is a group of diseases that affect the muscles and nerves, such as muscular dystrophies, multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). 

Conditions like MS can be triggered by genetic factors or an environmental trigger such as exposure to cold viruses. A person with a neuromuscular disorder may gradually experience weakness or paralysis. 

The signs are very individualized so each person has their own normal. The most common early symptoms include tingling, pain, and cramping in muscles around the chest. This could indicate a condition called myasthenia gravis. Other signs include difficulty lifting arms above your head, abnormally slow reflexes and breathing trouble.

2) Thyroid Conditions

Thyroid Conditions

The thyroid gland is a butterfly-shaped gland located at the base of the neck. Thyroid conditions such as underactive thyroid, hypothyroidism and Hashimoto’s disease are common causes for weakness in arms. Left arm weakness with chest pain may need immediate medical attention. Nerve damage or compression in the neck or upper back is another possible cause for muscle weakness in arms. 

A variety of other illnesses can affect this body part; diabetes is one condition that decreases blood flow to muscles and can lead to left arm weakness. Brain tumors are another source of left arm weakness and should be considered if a patient has recently been diagnosed with cancer or another neurological disorder.

3) Autoimmune Diseases

Autoimmune Diseases

Autoimmune diseases, such as Graves’ disease, myasthenia gravis, and Guillain-Barré syndrome, are treatable but they can be complicated. 

Graves’ disease is an autoimmune condition that affects the thyroid gland and typically develops after age 30. 

Myasthenia gravis is an autoimmune condition that causes the muscles to become weak because the body mistakenly attacks a specific type of protein called acetylcholine receptor found on cells of muscle fibers. 

Guillain-Barré syndrome is an autoimmune disease where a person’s immune system damages the myelin sheath, which protects nerve cells from damage and slows down transmission between nerves and muscles.

4) Stroke

Stroke

If there is a weakness on one side of the body and it lasts for more than two hours, you should seek medical help. Be aware that a stroke may happen with chest pain. 

These four risk factors should be avoided: smoking, high blood pressure, obesity, and diabetes. Drinking excessively could also cause problems. Other possible causes of muscle weakness in arms can include repetitive strain injury, nerve damage or compression in the neck or upper back or blockage in the bloodstreams.

It’s important to know these risks so that we are proactive about preventing problems!

5) Electrolyte Imbalances

Electrolyte Imbalances

An electrolyte imbalance such as hypokalemia (potassium deficiency), hypomagnesemia (magnesium deficiency), or hypercalcemia may be the cause. Symptoms may include dizziness, a weak grip, and fainting spells. Other signs may be nausea, confusion, muscle cramps and constipation. 

Left arm weakness with chest pain may need immediate medical attention.
