Vomiting and nausea are themselves not illnesses, but complications and complaints related to a variety of conditions. Dehydration can occur as a result of vomiting or nausea, especially with regard to motion sickness or cancer therapy. Morning sickness, which occurs during pregnancy, can also lead to vomiting and nausea. Nausea is an unpleasant, queasy feeling in the throat or stomach. The word vomiting refers to the emptying of the stomach contents through the gag reflex. Retching occurs when the stomach and esophagus move without vomiting occurring.
Vomiting is a reflex that is triggered by the brain. The body begins the vomiting sequence in response to stimuli such as taste, smell, illness, emotion, injury, pain, infection, motion and dizziness. Some other changes in the body can lead to the occurrence of vomiting. For example, anorexia, bulimia, viruses, food poisoning, vertigo, motion sickness and appendicitis are all potential triggers for vomiting. Additionally, vomiting might be caused by head injuries, migraine, brain tumors, brain infections and hydrocephalus.
Some medications can also lead to vomiting and nausea. Nausea is not normally an allergy but an unwanted side effect of medication. Medications used to treat conditions such as cancer often cause vomiting and nausea. Anesthesia can also lead to the occurrence of vomiting and nausea.
Some other internal conditions might be the root cause of vomiting or nausea. This includes conditions like stomach blockage, stomach bleeding and infection of the intestines. Also, if your body has a lack or excess of body chemicals and minerals, this might result in nausea. The cause of nausea and vomiting may also be down to the consumption of alcoholic beverages such as wine, liquor and beer. Pregnancy can also lead to vomiting and nausea. As regards pregnancy and nausea and vomiting, the condition (morning sickness) normally only lasts for the first few months of pregnancy, but it is possible for the condition to remain for the entirety of the pregnancy.
Prevention of nausea
In order to prevent nausea from occurring, it is advisable to avoid activities or substances that are triggers for these conditions. Drinking alcohol would be one example of this. Motion sickness that occurs while traveling can be alleviated by staring or fixating on a particular object on the horizon. Try traveling forwards when on a train. Dramamine is a medication that can help prevent the occurrence of motion sickness. Remember to follow the instructions as indicated on the label.
