Do you feel tired all the time for no obvious reason? Though in most cases fatigue could be nothing beyond normal sleep deprivation; in some cases, it may be a sign of some serious health concern. Here is a list of few health problems that could possibly be the culprits behind your chronic exhaustion.

#1 Hypothyroidism

Constant exhaustion and fatigue are common symptoms of hypothyroidism. Thyroid glands can play tricks with hormones as they control several body functions. Hypothyroidism occurs when there is not enough thyroid hormone in the body. Alongside fatigue, this disorder causes several other subtle and non-specific symptoms that are often ignored, such as hair loss, memory loss, and constipation. A blood test can confirm hypothyroidism and it can be effectively managed with synthetic thyroid hormone treatment.

#2 Anemia

The prolonged feeling of exhaustion signals anemia, which is caused by the deficiency of hemoglobin (Hb) in the body. Anemia can be easily diagnosed with a simple blood test performed by a doctor. 

#3 Depression

If you ever experience sort of unrelenting fatigue that doesn’t go away with resting, it’s alarming! Fatigue is certainly a subjective symptom with umpteen causes, but you need to be wary if it doesn’t follow any physical effort or lack of sleep. Such obscure fatigue may indicate reduced pumping ability of your heart. If there is any such prolonged feeling accompanied by weakness and shortness of breath, you should see your doctor to rule out congestive heart failure!

#7 Fibromyalgia

However, if you come across distinct pain or tenderness locations on your body it could be fibromyalgia.
