Nausea is a common symptom of a stomach infection.
Many things can randomly cause nausea. Most commonly, nausea is the result of a stomach infection, but it can also be associated with factors such as hormonal imbalances, lack of sleep, brain injury, and stress. If an obvious cause of nausea cannot be identified, it is advisable to see a doctor, as feeling nauseated can be a sign of a serious medical complication. A doctor can perform an evaluation to find out why a patient feels sick and develop a treatment plan to address the underlying cause.
Emotional stress can cause nausea.
Random nausea is often associated with a stomach infection. Whether mild or severe, if bacteria, viruses, and other organisms enter the gastrointestinal tract, patients often feel sick to their stomach. Also, serious infections in other parts of the body can cause nausea. Certain medications such as chemotherapy, medications used for general anesthesia, and antibiotics can also randomly cause nausea. These side effects are usually reported ahead of time so patients know to watch for them.
Pregnant women often feel nauseated.
Imbalance associated with balance disorders can be a cause, as can fatigue, stress, or extreme emotional distress. Some people with anxiety disorders and other psychiatric conditions develop random nausea as a symptom. Hangovers, when people feel sick after drinking too much alcohol, are also associated with nausea, and people can also experience nausea as a result of eating or drinking too much, or not getting enough food and water. Certain conditions, such as diabetes, are also linked to an increased risk of nausea.
Migraines can be the cause of random nausea.
Hormonal imbalances, such as those associated with pregnancy, are associated with nausea. People with odor sensitivities can also feel sick when exposed to strong odors, and nausea can also be a symptom for people with conditions like post-traumatic stress disorder. When they experience panic attacks, they may feel sick or throw up. People can also develop motion sickness as a result of motion sickness when traveling in cars, boats, trains, or planes, and motion sickness can strike at any time. Head injuries can also cause nausea and can develop minutes, hours, or even days after the initial injury.
Eating or drinking too much can cause nausea.
When someone feels nauseated, it can be helpful to lie down in a quiet environment and drink something carbonated to settle the stomach. The cause of random nausea should be identified to determine if further treatment is needed. Someone who feels unwell after surgery, for example, just needs to rest while the body gets rid of the rest of the anesthetic. Someone experiencing nausea for no apparent reason could be experiencing extreme dehydration, kidney failure, or other serious medical complications that need to be addressed.
