When a person experiences nausea, he usually feels as if he needs to vomit. Often, people who become nauseated describe feeling sick to their stomachs. In addition to a general feeling of queasiness, a person may experience other nausea symptoms. Among the most common are increased sensitivity to smells, loss of appetite, and abdominal bloating; some people may also feel the urge to belch or experience heart pounding. A bad taste in one’s mouth or increased saliva production may also be included among the most common symptoms of nausea.
The most common symptom of nausea is the feeling that an episode of vomiting will begin soon. This doesn’t mean a person who feels nauseated will vomit however, since a person can experience even severe nausea without vomiting. Nausea can be hard to describe, but many people who experience it say they feel queasy. Others say they feel sick to their stomachs.
Smell sensitivity and appetite loss are also among the most common nausea symptoms. A person who becomes nauseated often loses his appetite and may have a difficult time consuming any type of food or beverage. This can be a problem, as eating a bland food, such as crackers, may sometimes help to relieve nausea. In some cases, a person who feels nauseated is also sensitive to smells. Even smells that he normally enjoys, such as food or perfume, may make his nausea worse.
Abdominal bloating may also occur along with other nausea symptoms. In such a case, the affected person typically has the sensation of being overly full, and the bloating may even be visible. This symptom is usually caused by the presence of intestinal gas.
Many people feel the urge to belch or experience heart pounding when they become nauseous as well. In some cases, though not always, releasing gas in this manner may help a person feel better. Heart pounding may occur as well, especially when nausea is severe. In fact, some people experience heart pounding right before an episode of nausea turns into vomiting.
An individual may also have nausea symptoms that affect the way his mouth feels or tastes. For example, some people notice a sour taste in their mouths when they feel nauseated or note that their mouths feel dry. In other cases, however, a person’s mouth may seem to fill with increased saliva when he’s nauseated. Unfortunately, swallowing this increased saliva sometimes may make nausea symptoms worse.
