Muscle Fatigue: Symptoms, Causes, and Treatments

Muscle Fatigue Symptoms, Causes, and Treatments – Extreme tiredness followed by a decline in muscle performance is called muscle fatigue. It affects your professional and personal life by causing multiple health risks, such as disruption in normal physical and cognitive processes.

Let’s understand the causes and negative consequences of fatigue on the body.

Symptoms of Muscle Fatigue

Fatigue can cause a range of negative impacts on your physical and emotional health. The main signs of fatigue are:

  • Extreme tiredness
  • Muscles weakness and pain
  • Weak immunity
  • Constant headache and dizziness
  • Lack of concentration and decision-making ability
  • Depression

Causes of Muscle Fatigue

Sedentary Lifestyle

An inactive lifestyle can cause a loss of muscle strength due to poor blood circulation throughout the body. So, you may experience low oxygen and nutrient flow, leading to body pain and tiredness.


Usually, aging is associated with reduced mobility and specific health problems. However, following a healthy lifestyle, such as proper exercise, vitamin intake, and a healthy diet can help prevent the possibility of muscle weakness in old age.

Impaired Immune System

The long-term extreme tiredness disrupts the immune system functioning. Resultantly, the body can’t resist frequent infections and chronic health problems.


Anemia is when a patient lacks enough healthy red blood cells. Iron is the major component of hemoglobin that carries oxygen throughout the body. Oxygen depletion makes your body exhausted; hence, you may suffer from shortness of breath, dizziness, or extreme tiredness. Malnutrition, pregnancy, menstruation, and infectious diseases contribute to developing anemia.


Depression can intensify physical and mental fatigue by increasing the stress on your muscles. It is often associated with hormonal imbalance; your body needs to transmit chemical messages to muscles and nerves. A disturbance in the signal transmission process can cause muscle stiffness and pain. Moreover, sleep disturbance due to depression also exerts pressure on the body, causing muscle weakness.

Certain Chronic Diseases

Sometimes, muscle fatigue can be the sign of a chronic health problem such as:

  • Cancer
  • Hypothyroidism
  • Muscular Dystrophies
  • HIV
  • Rheumatoid Arthritis
  • Chronic Kidney and Liver Disease

Treatment Options for Muscle Fatigue

There are multiple treatment options for muscle fatigue, the most common are listed below:

Healthy Diet and Enough Water Intake

Eating a balanced, healthy diet and drinking at least 6-8 glasses of water can improve your metabolism and prevent muscle fatigue. Make sure to add a balanced proportion of proteins, carbohydrates, and fats to your diet to prevent the adverse outcomes of malnutrition.

Regular Exercise

A sedentary lifestyle is a primary cause of muscle fatigue. However, regular exercise, yoga, or running can boost your metabolism, improve blood circulation, and appetite.

Multivitamins Intake

Sometimes lack of essential nutrients can cause muscle fatigue. Research shows that vitamin D deficiency can cause rickets, osteoporosis, and cardiovascular issues. So, you may consider taking multivitamins such as Diamond Glow to help relieve the symptoms. Supplement intake can improve your energy level and muscle and bone strength.


Over-the-counter medicines for pain and inflammation can relieve the symptoms of tiredness. Treating thyroid dysfunction can also be beneficial to restore muscle strength.


Muscle fatigue is a painful problem that interrupts your daily healthy activities. It can be temporary or long-term, depending upon the underlying cause. Consult your doctor, who’ll diagnose its reason and suggest a proper treatment plan.
