Related to nausea: dizziness


1. an unpleasant sensation vaguely referred to the epigastrium and abdomen, with a tendency to vomit. Nausea may be a symptom of a variety of disorders, some minor and some more serious.

Nausea is usually felt when nerve endings in the stomach and other parts of the body are irritated. The irritated nerves send messages to the center in the brain that controls the vomiting reflex. When the nerve irritation becomes intense, vomiting results.

Nausea and vomiting may be set off by nerve signals from many other parts of the body besides the stomach. For example, intense pain in almost any part of the body can produce nausea. The reason is that the nausea-vomiting mechanism is part of the involuntary autonomic nervous system. Nausea can also be precipitated by strong emotions.
2. a nursing diagnosis accepted by the North American Nursing Diagnosis Association, defined as an unpleasant, wavelike sensation in the back of the throat or epigastrium, or throughout the abdomen, that may or may not lead to vomiting.

Patient discussion about nausea

Q. Nausea and Migraine Since yesterday I have migraine and feel very nauseous. I tried to take my regular meds but the nausea still won't go. I can't get to my doctor until tomorrow, and the nausea and migraine is making me feel really bad. Is there anything I can do to treat the nausea? What about OTC meds? Do you know any that may be helpfull?

A. What I do when I have nausea is drinking a can of Coke (the regular, not diet or caffeine-free). If that doesn't help, I have some anti-nausea OTC meds I use.

There are also very good prescription meds, but you need to see the doctor for that.

A friend of mine says that what helps him is drinking very hot water (as hot as he can tolerate), so if other things doesn't help you may want to try this…

Q. Could nausea harm the baby? Hi everyone, I am in first trimester end stage. I live with nausea from day 1 of my pregnancy. Every morning is a great battle for me. I do know that nausea is common during pregnancy but need to know when I will be alright. Could nausea harm the baby?

A. Hey, justin.. In normal condition, the ‘nausea and vomit’ feeling will be gradually decreasing by the age of 14-16 weeks of pregnancy (so you will feel less of that nausea feeling soon). If it still happens after the 1st trimester, or if the vomit is becoming worse, then a complete work up should be done.

Go see your OB-GYN doctor to make sure either your case is a normal one or you're experiencing the "hyperemesis gravidarum".
Hyperemesis gravidarum means the severe form of ‘morning sickness’ that will affect the balance health level of the pregnant mom. The treatment will firstly concern about the need of rest for the affected mother, and replacing the fluids that had been lost before. Some additional antiemetics and antihistamine, and even corticosteroids can be useful in treating a patient. Close monitoring is important in this case.

Q. How to stop feeling nauseous during my pregnancy? I am pregnant and feel sick all the time. Any remedies to recommend?

A. Very rich and spicy foods can cause nausea so try to stay away from them. Eat smaller meals and more frequently, drink tea and eat toasts which are good against nausea.
