Nausea and vomiting can be caused by gastrointestinal disease, viruses, bacteria, improper hand washing, morning sickness during pregnancy, excessive alcohol consumption, and medication side effects or personal sensitivity.
There are many conditions that can cause nausea and vomiting, but gastrointestinal disease is one of the most common. For example, a person who gets a stomach virus may get stomach sick. Morning sickness and excessive alcohol consumption can also cause these symptoms. Sometimes medications, both prescription and over the counter, can also make an individual ill. In some cases, they may be a known side effect of the drug, but in others, they may develop because an individual has a personal sensitivity to its ingredients.
The most common cause of nausea and vomiting can be gastrointestinal disease. For example, a person may become ill after contracting a virus from another person or consuming bacteria that has contaminated improperly prepared or handled food. Also, people often develop gastrointestinal illnesses because they don’t observe proper hand washing techniques. In such a case, a person may accidentally have fecal matter in their mouth, not realizing it was even on their hands. This can also happen if his food is being prepared or served by someone who hasn’t washed their hands properly.
When a woman is pregnant, hormonal changes, sensitivity to smells, and a more sensitive digestive system can cause her to develop morning sickness. Morning sickness often seems to come on for no reason and doesn’t always happen in the morning. A woman may experience nausea and vomiting in the afternoon, evening, and throughout the night, although these symptoms tend to be more common in the morning.
Drinking too much alcohol is another common cause of nausea and vomiting. Often people overestimate the number of alcoholic beverages they can consume without getting sick. When a person drinks to excess, they may begin to feel nauseous, and the nerves that control their gag reflex may be dulled. This makes him more likely to throw up, which is good for the body because it gets rid of the excess alcohol. When the body is unable to get rid of the excess alcohol in this way, or when vomiting does not eliminate enough alcohol, the affected person may develop alcohol poisoning.
Many medications can also cause a person to have an upset stomach, and several antibiotics are particularly notorious for this symptom. Sometimes, however, a person is sensitive to a drug, even if it doesn’t normally cause stomach pain. In some cases, eating before taking medications can help prevent this problem.
