Nausea and fatigue are the common symptoms of an upset stomach or fever. Both Nausea and fatigue occur one after the other or together, yet they are different.

What is Nausea?
As mentioned above, nausea is a condition of extreme abdominal discomfort accompanied by the need to vomit. As this condition is non-specific, it has many causes.
The most common cause of Nausea is a disruption in the diet, food poisoning, sleep deprivation, etc.
Apart from these minor causes, there may be severe abdominal infections that can prove to be a disaster if not treated immediately.
The word nausea is derived from the Greek word- Nausia, which means motion sickness. Physical factors can cause nausea, but a person can experience nausea even through mental conditions like depression.
The vital causes of nausea are food poisoning and gastrointestinal infections. Minor yet frequent cases of nausea are reported due to pregnancy and medications.
Nausea is not a gender-specific disease. It can affect anyone. The only type of nausea that is women-specific is morning sickness in pregnancy.
Some medications can also cause nausea as a side effect. Majorly, patients undergoing chemotherapy during cancer treatment and patients undergoing migraine treatment face nausea as a symptom.
Sometimes, nausea can also be caused due to mental conditions like depression and anxiety, as patients facing these issues resort to over-eating, which leads to Nausea.
Severe cases of nausea are treated with proper diagnostic tests and treatment, while non-severe cases can be treated by some antiemetics (medicines used to treat nausea).
What is Fatigue?
As aforementioned, fatigue is a condition wherein a patient has extreme tiredness and does not improve even after sleeping for the required hours. Its major causes are stress, anxiety, etc.
We can majorly classify fatigue into physical and mental fatigue. Physical activity can cause physical fatigue or even through long hours of travelling- jet lag.
Mental Fatigue can have many reasons like stress, anxiety, depression, etc.
Physical Fatigue is when a person’s muscles and bones have no energy to perform better. Hence the physical ability to do any activity decreases.
Initially, the muscles slowly start degrading, and this phenomenon varies with every person. Some people have better metabolism and stamina.
Hence, their muscles don’t degrade in the initial phase of fatigue. It also depends on the number of hours a person gets to sleep. Better sleep guarantees lower chances of fatigue.
On the other hand, Mental Fatigue is a severe type of Fatigue, as it affects not only the cognitive ability but also the physical performance of a person.
It decreases the concentration span and increases lethargy.
Mental Fatigue can also cause many accidents, as patients suffering from it feel sluggish and sleepy. Mental fatigue can also be a symptom of a severe neurological disorder.
Patients suffering from Mental Fatigue cannot maintain consciousness for a prolonged period.
Fatigue is a complex disorder. Hence there is no peculiar cause for the disease. It has a wide range of causes, diagnoses, and treatments.
Patients suffering from Fatigue are instructed to regulate their sleep cycle also reduce their stress levels. In some cases, the patients are prescribed sleeping pills.
