Nausea is a common sensation that makes patients feel that vomiting may occur.
Sometimes nausea does make people vomit, but there are also many patients with nausea that do not vomit.
This article summarizes 12 common causes of nausea and discusses some of them.
12 common causes of nausea There are many causes of nausea.
Some common causes include: viruses such as influenza or norovirus (stomach cold) gastrointestinal diseases such as irritable bowel syndrome (IBS) stress or anxiety motion sickness pregnancy phobia migraine food poisoning certain drugs such as hormones Contraceptives or beta-blockers have problems with the inner ear, such as labyrinthitis or vestibular neuritis, thyroid disease, eating disorders, and some of the reasons are discussed below.
Gastrointestinal infections and nausea Gastrointestinal infections (such as infections caused by food poisoning or viruses) are one of the most common causes of nausea.
Symptoms may include nausea, stomach pain or cramps, vomiting, and diarrhea.
Food poisoning occurs when the human body ingests food or beverages containing viruses, toxins or bacteria (such as Salmonella and E.
coli).
Other gastrointestinal viruses (such as norovirus or rotavirus) occur because of close contact with sick people.
These infections can usually be cleared at home on their own.
Adequate intake of water and electrolytes is very important to prevent dehydration, especially for young children.
Digestive system diseases and nausea The following digestive system diseases can cause nausea: Gastritis: Gastric acid or Helicobacter pylori often cause inflammation of the stomach, which can lead to gastric ulcers.
Gastroparesis: Certain drugs or nerve damage usually cause gastroparesis, which is common in people with diabetes.
The rate of gastric emptying in patients with gastroparesis is much slower than normal.
Gastroesophageal reflux disease: can cause chronic acid reflux and indigestion.
IBS: Can cause stomach cramps, accompanied by diarrhea or constipation.
Celiac disease: An autoimmune disease that causes symptoms due to the intake of gluten-containing foods.
Gallbladder disease: including gallstones and so on.
Pancreatic diseases: including pancreatitis and so on.
Normally, nausea is not the only symptom of chronic digestive diseases.
Patients may also experience the following concomitant symptoms: bloating or fullness, gas or belching, heartburn or indigestion, diarrhea and/or constipation, abdominal pain and cramps, reaction or intolerance to specific foods or food groups.
Diagnosis and treatment of digestive diseases vary from disease to disease, and may involve combination medications, diet or lifestyle changes, or in some cases, medical procedures.
Mental health is closely related to nausea, mental health and digestive health.
People with poor mental health can experience digestive symptoms, including nausea.
Similarly, stress can exacerbate digestive symptoms.
People who often feel stressed, anxious, or panic may suffer from anxiety disorders.
Symptoms of anxiety include: nausea, rapid heartbeat, fast or shallow breathing, choking in the throat, sweating, dizziness, and muscle tension.
Severe anxiety can also cause panic attacks or, in some cases, fainting.
For example, people who are afraid of needles or blood may experience nausea, dizziness, and loss of consciousness.
This is called vasovagal syncope.
People also feel fear of nausea and vomiting itself, which is clinically called vomiting phobia.
The treatment of anxiety disorder usually includes talk therapy, symptomatic medication, or both.
Nervous system diseases and nausea Changes in the brain and nervous system can cause nausea in many ways.
One of the most common neurological diseases that cause nausea is migraine.
This is a disease that causes moderate to severe headache attacks, accompanied by other symptoms: sensitivity to light or sound, nausea, vomiting, migraine with aura.
Some patients also experience asymptomatic migraine.
There are several treatments for migraine.
For occasional or less severe attacks, patients can take over-the-counter (OTC) pain relievers and avoid triggers.
For severe or frequent migraines, patients may need to receive preventive medication or other treatments.
Summary Nausea can exist alone, or it can be accompanied by other clinical manifestations, as described above.
When nausea is accompanied by vomiting and general signs (especially fever), it is necessary to first identify the presence of potentially serious diseases (such as intracranial hypertension, meningitis, occlusion, etc.
).
Nausea will reduce the patient's quality of life and reduce the patient's concentration and work activity level.
Many clinical patients do not specifically treat nausea, but take rest to relieve and wait for the symptoms to subside.
In the case of not serious symptoms, patients can consider not using medical prescriptions for treatment, especially for recurrent patients whose causes have been identified.
There are many drugs with anti-nausea effects.
Although treatment for the cause is necessary, some short-duration drugs can help relieve symptoms, especially antihistamines, anticholinergics, and phenothiazine derivatives.
