What is Nausea?

Nausea is an uneasy sensation in the stomach which includes the urge to vomit. Nausea is common and is usually not a matter of concern. However, if you are experiencing nausea too frequently or for a long period of time, it may symbolize a more serious underlying condition. In this article, we mention the probable causes of nausea, its treatment and prevention.

Causes of Nausea

It is quite common and a variety of conditions may cause it. The common causes are:

  • Stress

When you feel stressed or anxious, your body releases hormones which makes you feel restless and nauseous. 

  • Pregnancy

A part of ‘morning sickness’ in pregnancy, the exact cause of nausea during pregnancy is not known yet, but the pregnancy hormones and sensitivity of stomach are expected to have a connection to it. It is usually a symbol of a healthy pregnancy. 

  • Drug abuse

Drugs affect the nervous system which stops it from functioning normally, inducing effects like vomiting. Drug abuses can be fatal. 

  • Motion sickness/ Sea sickness

Nausea during motion or due to sea is caused by the imbalance of the ear, the eyes and the sensory receptors. It is quite unpleasant but isn’t life-threatening. 

  • Excessive alcohol

Alcohol interferes in the normal working of the body and especially the stomach, which causes nausea. Excessive alcohol is also known to cause nausea by irritating the stomach lining. 

  • Gastroesophageal reflux disease ( GERD)/Acid reflux

These conditions occur when the contents of the stomach travel backwards between the oesophagus and the throat. They cause conditions like heartburns. 

  • Binge eating

Binge eating hampers the normal functioning of the stomach since the stomach has a limited capacity. It causes the food to rise up which induces nausea. 

  • Migraine/Vertigo

Migraine or vertigo makes one feel restless which upsets the stomach and causes nausea. 

  • Intestinal blockage

A blockage cuts off blood supply from parts of the intestine which causes effects like nausea and bloating. 

  • Unpleasant odor

Strong or foul odors send signals to the brain which causes the cough and gag mechanism to work and thus, it occurs. 

  • Overactivity

Overactivity hampers blood flow in the stomach and causes nausea. 

  • Side effects of medications

Medicines such as NSAIDS irritate the lining of the stomach and causes nausea. It is also caused by the interaction of different medications or the inability to digest a medication. 

  • Certain allergies

Some allergies cause nausea, especially allergies from food. Our immune system induces a protective mechanism against those foods which results in vomiting. 

  • Concussion

Concussion affects body balance which induces nausea. Nausea resulting from these conditions should last a few hours and it usually heals on its own. If it lasts for more than 24 hours, medical supervision is advised.
