What are the Most Common Causes of Fatigue and Nausea?

Troy Holmes

Some of the common causes of fatigue and nausea include malnutrition, heat stroke, low blood pressure, and the flu. These symptoms typically correspond with serious health risks that should be reviewed by a medical professional. Fatigue refers to a situation where an individual becomes extremely exhausted, while nausea is an upset stomach and the feeling that a person might vomit.

The influenza virus typically affects humans in outbreaks that occur each year. This virus causes serious fatigue because the body's immune system becomes overwhelmed. Most flus last about 10 days, and during this time, it is important for affected individuals to drink water and nutrients. This helps reduce the chances of dehydration, which can increase these symptoms.

A poor diet is one possible cause of fatigue and nausea.

An unhealthy diet can lead to fatigue and nausea. When an individual does not eat enough essential vitamins, he can feel very tired because the body relies on healthy foods to work properly. The vitamin deficiencies that are most associated with these symptoms are primarily the B vitamins. Adding a multivitamin to a daily diet program may help a person feel better.

Excessive heat and dehydration are known to produce symptoms of fatigue and nausea as well. Heat stroke typically occurs when an individual does not monitor his body temperature or water consumption. When he becomes too hot or dehydrated, he cannot sweat fast enough to cool his internal body temperature. This can quickly lead to total collapse and eventual death if not resolved properly.

Low blood pressure can cause fatigue and nausea.

Low blood pressure is a situation where the body is not pumping enough blood to support the primary organs. This leads to fatigue and potential blackouts. Some common causes of low blood pressure include medicines, heart problems, dehydration, and diabetes. Many low blood pressure patients also experience symptoms of nausea.

Alcohol is a depressant, so drinking too much can cause tiredness. In addition, it causes the body to dehydrate, which causes fatigue. It also can quickly upset the stomach. The body typically treats alcohol like a poison, which can lead to vomiting. Some good counter measures for overindulging in alcohol include drinking water and electrolyte drinks. Drinking water after consuming alcohol can reduce the effects of a hangover since it helps the body in filtering the alcohol from the system and improves hydration.

Many pregnancies include periods of fatigue and nausea. This is typically based on hormone changes and possible nutritional deficiencies. Most mothers take daily prenatal vitamin supplements, which may help relieve tiredness.

@ddljohn-- Is she on any medications or supplements?

I'm a registered nurse and I work with cancer patients who are receiving chemotherapy and radiotherapy. Constant fatigue and nausea is one of the immediate side-effects of these treatments and generally last for several weeks even after the treatment is completed.

It's also a common side effect of many medications and sometimes supplements. Generally we doctors and nurses warn patients about the potential side effects before starting any medications and treatments. But not everyone reacts to medications in the same way. So even if your wife wasn't warned about any of the current medications she's on, or if fatigue and nausea is not listed as a common side effect, you could still be having these symptoms due to the medication.

The best thing to do in this case is to speak with your doctor to see if he or she can switch you to something else, or if a lower dose is necessary.

My wife has been having bad bouts of fatigue and nausea lately. She has an appointment next week with her doctor to see what's up. She actually had a check up six months ago and she didn't have any vitamin deficiencies at that time. So we have no idea what it could be. She is suspecting thyroid issues though because three people in her immediate family have thyroid disease. I guess we'll find out next week.

I remember that I used to get fatigue and nausea symptoms due to over-training when I used to work out a lot in college. If I reduced my work out hours and rested, it would go away on it's own. My wife doesn't do any heavy workouts though so it must be something else.

By the way, she isn't pregnant either. This was the first thing we checked for when she started getting these symptoms.

I get fatigue, dizziness and nausea a lot, especially when I forget to take my iron supplements. I have a serious iron deficiency. Last year, I started to faint way too often, 2-3 times a week. I would also feel sick, like I would vomit, and wouldn't eat properly. Of course this used to give me a lot of fatigue.

My family took me to the doctor for a checkup. The doctor couldn't believe my blood iron levels because it was too low. I was prescribed iron supplements and I have to take one every day.

Sometimes I forget to take them though and I start feeling very tired, dizzy and nauseated then. If I don't take my supplement right away, I can faint.
