When most people feel fatigued, they think that it is caused by exhaustion that may have occurred due to mental or physical activities. In some cases this may actually be true. However, in other cases, fatigue can be a symptom of something else. It could be symptom of a disease or it could indicate that you are over-working yourself. If you feel regularly fatigued, you need to consult a doctor.
Some of the symptoms of fatigue include general body weakness, inability to start or complete simple tasks, low energy, feeling tired even without having done anything, and in extreme cases fainting.
One of the most serious causes of fatigue is heart disease. This normally occurs before the disease gets properly diagnosed. You will start feeling tired even after carrying out just simple daily household tasks or doing basic activities such as walking. If you experience this, be sure to visit a doctor immediately.
Fatigue may be caused by hypothyroidism. This condition is normally very common, especially in women, although it has a tendency of going undetected unless tests are carried out.
Another frequent cause of fatigue is Anemia. This is especially common in women. It occurs due to excessive blood loss. It can occur after the delivery of a child, heavy menstruation flow or even fibroids. Anemia may also occur in men if excessive blood loss occurs such as bleeding due to an accident or injury. This condition may also occur due to insufficient iron in the body. If untreated, it can have very serious consequences and can even be fatal.
One of the least known causes of fatigue is urinary tract infections (UTIs). Most women would never associate fatigue as a symptom of UTIs since there are other more common symptoms of these infections. However, there are women who may not experience the other common symptoms such as the burning sensation during urination or vaginal discharges. Instead, these women will just start feeling tired more often.
If you are allergic to certain types of food, the most common reactions are immediate. However, there are other food allergies where an allergic reaction may not occur immediately. They may only occur after a prolonged period of time if the person keeps taking the food. One of the symptoms that may alert you to this type of food intolerance is, in fact, fatigue.
Fatigue may also be caused by certain lifestyle choices. For instance, too much caffeine may have this effect on some people. This is very risky due to the notion that most people try to use caffeine to boost their energy levels. There is therefore a high probability that a person may increase their caffeine intake without really realizing that this is the cause of their exhaustion problems.
Lack of sleep is also one of the causes of fatigue. This may occur if you suffer from sleep apnea. You may think that you are getting enough sleep when really you are not. Sleep apnea keeps you waking up repeatedly throughout the night. You may not even realize that you are doing this. However, if you wake up tired despite having slept for hours, you should consider the probability that you may be suffering from this condition.
Other causes of fatigue include kidney failure, liver disease, poor mental health, cancer and many others. The use of antidepressants for a long period of time may also cause fatigue. Seeking medical attention is advisable if you start experiencing fatigue more frequently. A doctor will carry out tests to identify the cause of fatigue and then administer the necessary treatment.
