There are many conditions capable of causing a person to experience nausea and sweating. These symptoms can be caused by everything from sudden illnesses and injuries to chronic conditions and emotional upheaval. Gastrointestinal illness may be among the most common causes of these symptoms. A person may also experience these symptoms during a heart attack or during an episode of anxiety or vertigo. Additionally, a person may sweat and feel nauseous after taking some types of medication.
While there are many things that may cause a person to experience nausea and sweating, an illness that affects the gastrointestinal tract may be the most likely culprit. For example, a person who has food poisoning may experience these symptoms before he develops such symptoms as vomiting and diarrhea. In some cases, a person may feel nauseous and begin sweating after taking a medication that upsets his stomach. Sometimes the sweating is a symptom of the digestive tract illnesses or condition. In some cases, however, a person may begin to sweat because he is emotionally upset over the illness.
Another common cause of nausea and sweating is a heart attack. Many people are most familiar with chest and arm pain as symptoms of heart attacks, but sweating and nausea are frequent symptoms as well. In fact, the symptoms of a heart attack may sometimes be mild enough that a person may focus on the nausea and decide he is suffering from indigestion or a digestive-related illness rather than having a heart attack. Sometimes the symptoms are vague or mild enough that a person may even attribute them to being overly tired.
Anxiety is another one of the common causes of sweating accompanied by nausea. For example, a person who has panic attacks may become nauseous, begin to sweat, and note a feeling of dread when he has a panic attack. Some people even have symptoms that mimic those of a heart attack. For instance, a person may have chest pain or a sensation of a heavy weight on his chest while he is having a panic attack. An individual need not have a panic disorder to experience these symptoms along with feelings of anxiety, however; some people may become nauseous and begin to sweat when they become occasionally anxious.
An individual may also experience nausea and sweating during an episode of vertigo. Vertigo is a type of dizziness in which a person may feel as if his environment has changed. For example, he may feel as if the room is spinning or the ground has tilted.
