What is nausea?
Nausea is a symptom in which there is discomfort in the upper part of the stomach with the desire to vomit. However, it is not always accompanied by vomiting. Medically, it is defined as the unpleasant feeling of wanting to vomit.
Both nausea and vomiting do not represent an illness but rather a symptom or sign of another disease.
Generally, nausea without vomiting usually disappears on its own. Otherwise, the general condition of the person could deteriorate. They are characterized by:
- An uncomfortable sensation in the throat.
- The sensation of heat and profuse sweating.
- Annoying sensation in the upper abdomen and chest.
- What is known as retching may appear as involuntary contractions of the abdominal and respiratory muscles with which vomiting may or may not be caused.
- The esophageal sphincter may relax, which allows vomiting to escape.
- For vomiting to appear, the abdomen, the diaphragm, and the trachea muscles are closed simultaneously.
Everyone at some point in their life has experienced this unpleasant sensation since it is a fairly common condition and a frequent reason for consultation in the emergency room. Once the cause is known and effectively treated, nausea will disappear.
The duration of nausea, then, will depend on the causes to be treated so that it can last from minutes to hours.
I’m nauseous but not vomiting: common causes.
Among the most common causes of nausea without vomiting are:
- Anxiety: People with anxiety are likely to be nauseous or have the urge to vomit. This occurs because the signal that activates vomiting and nausea is located in the brainstem. Its activation after nerve stimulation of the bulb, a product of some unpleasant stimulus, causes retching, sweating, and abdominal muscles to contract and the esophageal valve to open, preparing for vomiting.
- Migraine is another common cause of nausea; it also occurs after activating the medulla oblongata that is located in the brain. Migraine is a common neurological disorder in which severe headache occurs; in addition to nausea with or without vomiting, sensitivity to light may appear.
- Stress or fear: both can cause the body to function incorrectly. Fortunately, since fear is a temporary sensation, nausea will go away when the feeling of fear subsides. In the case of stress, it is essential to assess the underlying causes to treat them and that the symptoms disappear.
