Nausea is characterized by a feeling of needing to vomit, loss of appetite, sensitivity to smells, abdominal swelling, and other symptoms. It can be difficult to describe, but many people report feeling nauseous or sick to their stomach. Bloating, burping, and heart racing may also occur, as well as changes in taste or saliva production.
When a person feels nauseous, they usually feel like they need to vomit. Often, people who experience nausea describe feeling like an upset stomach. In addition to a general feeling of nausea, a person may experience other symptoms of nausea. Among the most common are increased sensitivity to odors, loss of appetite and abdominal swelling; some people may also feel the urge to burp or experience a heartbeat. A bitter taste in the mouth or increased saliva production can also be included among the most common symptoms of nausea.
The most common symptom of nausea is a feeling that a vomiting episode is starting soon. However, this does not mean that a person who feels nauseous will vomit, as a person can experience even severe nausea without vomiting. Nausea can be difficult to describe, but many people who experience it report feeling nauseous. Others say they feel sick to their stomach.
Sensitivity to smell and loss of appetite are also among the most common symptoms of nausea. A person who becomes nauseous often loses their appetite and may have difficulty consuming any type of food or drink. This can be a problem, as eating a bland food, like crackers, can sometimes help relieve nausea. In some cases, a person who feels nauseous is also sensitive to smells. Even smells that you normally enjoy, such as food or perfume, can make your nausea worse.
Abdominal bloating can also occur alongside other symptoms of nausea. If so, the affected person typically has a feeling of being overly full, and swelling may also be visible. This symptom is usually caused by the presence of intestinal gas.
Many people feel the urge to burp or feel their heartbeat when they are also nauseous. In some cases, though not always, releasing gas this way can help a person feel better. Heart racing may also occur, especially when the nausea is severe. In fact, some people experience their heart pounding right before an episode of nausea turns into vomiting.
An individual may also have symptoms of nausea that affect the way their mouth feels or tastes. For example, some people notice a sour taste in their mouth when they feel nauseous or notice that their mouths are dry. In other cases, however, a person’s mouth may feel full of saliva when they are nauseous. Unfortunately, ingesting this increased saliva can sometimes make nausea symptoms worse.
