Nausea is the feeling of wanting to vomit and feeling uncomfortable in the stomach. Even so, nausea is not always accompanied by vomiting. Nausea is generally a mild condition, but it can also be caused by a serious illness, such as kidney stones.

Nausea is not a disease, but a symptom caused by certain conditions. Nausea is a protective mechanism that indicates that the body is being attacked by germs or poison.

Causes and Symptoms of Nausea

There are various causes of nausea, both shaking, food poisoning, the influence of drugs or hormones , as well as due to early pregnancy. Here are the causes of nausea and accompanying symptoms:

  • Heartburn and stomach acid
    Heartburn and stomach acid can cause stomach contents to rise up into the esophagus causing nausea.
  • Bacterial or viral
    infections Viral and bacterial infections can cause nausea. The germs can enter the body through food or drink consumed. This condition is also called food poisoning .
  • Medicines
    Some medicines can cause nausea, for example chemotherapy drugs to overcome cancer. Therefore, pay attention to the content and method of use of the medicine to avoid nausea caused by the consumption of the medicine.
  • Motion sickness Motion
    sickness due to winding and bumpy roads can also cause nausea. This happens because the message sent to the brain is not consistent with the perception of the senses.
  • Certain
    diseases Some diseases can cause nausea, such as acute pancreatitis, gallstones , or kidney stones.

When should you go to the doctor?

Check with a doctor if nausea is accompanied by diarrhea, dehydration, vomiting , or lasts a long time. Also check yourself with a doctor if you experience nausea in early pregnancy .

Immediately check your child to a doctor if he experiences nausea for more than 1 hour, especially if accompanied by diarrhea, fever, dehydration, or unable to urinate for 4-6 hours.

Be alert and immediately seek medical help if nausea is accompanied by the following symptoms:

  • Vomiting that lasts more than 24 hours
  • Vomiting accompanied by blood , either bright red or coffee-colored
  • Severe headache or stiff neck
  • Fatigue, dizziness, or loss of consciousness
  • High fever
  • Blurred vision
  • Chest pain

Diagnosis of Nausea

The doctor will ask about the patient's nausea and other complaints that may accompany it, as well as the patient's medical history. In patients who experience nausea for days, the doctor can perform an examination on urine or blood samples.

Treatment of Nausea

Nausea can be eased by resting for a while or drinking water slowly. In addition, avoid heavy meals until the nausea subsides. If nausea is accompanied by vomiting, immediately drink electrolyte fluids to replace lost body fluids.

If the nausea does not subside, consult a doctor. The following are some examples of nausea drugs that are generally prescribed by doctors to deal with nausea:

  • Dimenhydrinate , to prevent or treat motion sickness
  • Granisetron , ondansetron , metoclopramide , and domperidone , to prevent nausea and vomiting after surgery
  • Granisetron , ondansetron , palonosetron , domperidone , olanzapine, and dexamethasone , to prevent nausea before and after chemotherapy
  • B ismuth subsalicylate , to overcome nausea due to gastroenteritis
  • Pyridoxine or promethazine , to overcome severe nausea and vomiting during pregnancy ( hyperemesis gravidarum )

Complications of Nausea

Unrelenting nausea can cause vomiting. If it occurs excessively, vomiting can cause a number of the following complications:

  • Dehydration
  • Electrolyte deficiency
  • Decreased food intake
  • Disturbance of acid-base balance

Prevention of Nausea

Prevention of nausea is to avoid the causative factor. Nausea can also be prevented by doing some of the following:

  • Avoid pungent smells.
  • Avoid seeing flashing lights for migraine sufferers.
  • Take anti-motion sickness medication before traveling.
  • Avoid heavy physical activity after eating.
  • Avoid eating spicy and high-fat foods.
  • Eat in small portions but often.
