Nausea and vomiting: infection or “neurology”?

Nausea
Nausea is a painful sensation of discomfort in the upper abdomen, esophagus and mouth; anticipation of vomiting. When describing such symptoms, patients say “I feel sick.” Sometimes the symptoms of nausea are less pronounced, in such cases they say “nauseous.” Nausea is often accompanied by weakness, sweating, and increased salivation. A person experiencing nausea may experience a decrease in blood pressure, become pale, and feel cold in the extremities.

Why do unpleasant symptoms occur?

Causes of nausea not related to illness include:

• Overeating and eating fatty foods . In this case, nausea appears after eating as a response of the body - it cannot cope with a “heavy” dish in terms of calories.
• Psychological factors. Constant stress, depression, and anxiety disrupt the overall metabolism in the body. Nausea occurs as soon as a person remembers an unpleasant experience or smells a familiar smell.
• Seasickness (motion sickness) . The receptors of the vestibular apparatus are irritated, a feeling of nausea occurs, which may be accompanied by vomiting.
• Pregnancy. Nausea and dizziness are observed in the first and second trimester of pregnancy. The sensation may progress to vomiting, but relief occurs on its own as the body adapts to pregnancy and the baby grows in the womb.
• In women, an unpleasant symptom often occurs during the premenstrual period.
• Impact of third party factors. An acute feeling of nausea can occur due to exposure to chemicals, medications, overheating, increased body temperature and other reasons.

Constant nausea often indicates the presence of various diseases. In some cases, depending on the stage of development of the disease, the feeling may occur periodically. He is called:

• Diseases that require urgent surgical intervention: appendicitis, acute pancreatitis, peritonitis of the gastrointestinal tract, intestinal obstruction.
• Chronic diseases associated with dysfunction of the gastrointestinal tract: peptic ulcer, cholecystitis, irritable bowel syndrome.
• Intestinal infections: enterovirus and rotavirus, cholecystitis, food poisoning.
• Liver diseases: hepatitis, cirrhosis.
• The presence of a foreign body in the abdomen (esophagus, intestines).
• Food allergies.

Severe headache and nausea can bother a person after traumatic brain injury, hypertension, diseases of the endocrine system, migraine, and after chemotherapy.

Development mechanism

The occurrence of nausea is based on the activation of the neural arc of the gag reflex at a level insufficient for the onset of vomiting. The most common trigger for a reflex reaction is irritation of peripheral receptors located in the digestive and a number of other organs. Less commonly, the reflex is activated due to stimulation of the vomiting center, the effect of toxic substances or metabolites on the receptive zone of the bottom of the fourth ventricle of the brain. In a number of conditions (for example, pregnancy), a combination of several triggering factors is possible.

Regardless of the reasons that provoked the development of nausea, the mechanism of its formation is based on a single pathophysiological process. When the vomiting center is activated, the tone of the muscular lining of the stomach decreases, its peristalsis slows down or completely stops. A simultaneous increase in the tone of the duodenum and the proximal part of the jejunum causes duodenogastric reflux. An increase in the volume of gastric chyme leads to reflex relaxation of the cardia, contraction of the antrum, diaphragm and intercostal muscles, which is perceived as a urge to vomit.

Clinical picture

Nausea, depending on the cause, may be accompanied by other symptoms.

• When eating fatty foods: abdominal pain, vomiting, weakness, drowsiness.
• Nausea is often observed in a child as a reaction of the body to an allergen. Adults and children equally experience: rash, redness, diarrhea, flatulence, runny nose, dry cough.
• In case of poisoning: flatulence, diarrhea, headaches, weakness.

In diseases, depending on the diagnosis, the manifestations differ:

• Diseases of the liver and gastrointestinal tract often resolve with vomiting, weakness, and body temperature rises to 39 degrees. There is a feeling of heaviness in the abdomen, diarrhea/constipation, and flatulence.
• Appendicitis will almost always be accompanied by acute pain in the lower abdomen and increased body temperature.
• With diseases of the cardiovascular system, nausea in the morning can turn into weakness in the afternoon, headaches, dizziness, and loss of consciousness.

Normally, in the absence of health problems, a person needs to eliminate the cause of the symptom. For example, exclude exposure to odors, consult a doctor about the need to take medications that calm the nervous system (if we are talking about psychological factors). Take a sorbent to remove toxins from the body in case of allergies or poisoning.

If, after treatment, pain, dizziness and nausea, as well as other accompanying symptoms, do not go away, you should urgently consult your doctor or gastroenterologist.
