Nausea – Causes, Treatment and More

Nausea is abdominal discomfort and a sense of vomiting. Nausea is a discomfort caused by vomiting which often occurs prior to vomiting. There are many causes of the disease and it is often preventable.

What causes nausea?

Nausea may arise due to various causes. Some people are very susceptible to movement, certain foods, certain medicines or the effects of certain diseases. All of those things cause nausea. Common reasons for nausea can be found below.

Heartburn or gastroesophageal reflux disease (GERD)

Heartburn or gastroesophageal reflux disease (GERD) May raise the contents of your stomach upwards (regurgitate) your esophagus when you eat. This leads to a burning sensation which causes nausea.(1)

Infection or virus

Bacteria or viruses may affect the stomach and lead to nausea. Food-borne organisms can cause food poisoning. Virus infections can cause nausea as well.


If you take certain medications, for example, cancer treatments such as chemotherapy can disturb your stomach and cause nausea. Be sure to read the medication information carefully for any new therapy you may be taking.

Reading this information and taking suggestions from your physician about the medications and treatments you are taking can help you reduce the nausea associated with the medications.

Motion sickness and seasickness

Motion sickness and seasickness may be caused by difficult driving on a vehicle. This movement may cause the messages sent to the brain to not synchronize with the senses, resulting in nausea, dizziness, or vomiting.


Overeating or consumption of certain foods, such as spicy or fat-rich foods, disrupt the stomach and cause nausea. Eating foods that are allergic to you may cause nausea as well.


Severe pain can cause nausea as well. That’s true of some painful conditions like pancreatitis, gallbladder stones, and kidney stones.


Ulcers, or wounds to the stomach or mucous membrane of the small intestine, can cause nausea. When food is eaten, an ulcer may cause burning and sudden nausea.

Nausea is also a symptom of many other health problems, including:

  • heart attack
  • intestinal blockage
  • liver cancer
  • benign paroxysmal positional vertigo (BPPV)
  • ear infection
  • liver failure
  • meningitis
  • migraine

When to seek medical help

Choose immediate medical assistance if your nausea is accompanied by symptoms of a heart attack. Symptoms of a heart attack include overwhelming chest pain, abnormal heartbeat, anxiety, severe headache, jaw pain, sweating or pain in the left arm.

You should also request emergency medical assistance if you experience nausea combined with severe headache, neck stiffness, difficulty breathing or confusion. Check with a doctor if you suspect you have ingested a toxic substance or if you are dehydrated.

Consult your doctor if you have not eaten or drank for more than 12 hours as a result of nausea. You should also check with your doctor if your nausea does not decrease within 24 hours of taking any steps without a prescription.

Always check with a doctor if you are worried about having a medical emergency.

What is the treatment for nausea?

The treatment of nausea varies according to the cause.

Sitting on the front seat of a vehicle can help relieve motion sickness. Motion sickness may also be treated with medicines such as dimenhydrinate (Dramamine), an antihistamine, or by applying a patch of scopolamine to relieve sea sickness.

Taking medicine to mark the base cause of nausea can also be useful. For example, gastric acid reductors for GERD or analgesic drugs for serious headaches.

Maintaining your hydration may help reduce dehydration after your nausea subsides. This includes the intake of suitable drinks such as water or drinks containing electrolytes.

When you begin to re-consume food, it helps to follow the BRAT diet (bananas, rice, apple sauce, and toast) Till your stomach becomes more stable.
