What Causes Nausea For No Reason

If a person is nauseated they might feel sweaty and/or weak and experience excessive salivation. Nausea often results in vomiting. Though it’s not necessary to be overly concerned about nausea (and/or vomiting), it can of course indicate a serious health condition.

Although nausea is not specifically a disease in and of itself, in can be related to many disorders of the digestive system. In fact there is a long list of various disorders known to cause nausea as a symptom, including all of the following

  • Migraine headaches: A migraine is a kind of headache which is often experienced (not all the time and not for everyone) on one side of a person’s head. A migraine can lasts anywhere from just a couple hours to as much as seventy-two hours, and often includes nausea and/or vomiting. Some people experience varying degrees of light and sound sensitivity, as well. The pain has many descriptions, but “throbbing” is a kind of pain often associated with a migraine. And there are many kinds of migraines, and symptoms vary, but nausea is a common symptom for many kinds of migraines.
  • Gastroesophageal reflux: a condition (also known as GERD or acid reflux) in which stomach acids come up and enter back in the esophagus. Without treatment of Gastroesophageal refulx other complications can arise and develop, including esophagitis, esophageal strictures, as well as a condition called Barrett’s esophagus,
  • Non-ulcer dyspepsia: a condition in which there is discomfort in a person’s upper stomach that is NOT caused by an ulcer
  • Gastroparesis: a condition related to nerve or muscle problems in the stomach which can lead to digestion to slow down
  • Bowel obstruction: an issue that manifests when brain signals can cause food to stop moving through the digestive system, even though there isn’t an actual blocked bowel
  • Autonomic Dysfunction: Also known as Autonomic Failure or Autonomic Neuropathy, this is a condition in which areas of the brain that are involved in controlling digestion stop functioning well. When the autonomic nervous system, which is responsible for bodily balance and overall bodily well-being, doesn’t regulate itself correctly this condition occurs and can affect blood pressure, heart rate, digestion, urinary function, sexual function, and temperature control. Some people that suffer from autonomic dysfunction have issues with many body systems simultaneously, while other people’s issues are more limited to problems with digestion, temperature control, and/or heart rate.
  • Postural Orthostatic Tachycardia Syndrome: a condition in which there is an abnormal change in heart rate when a person changes their posture

In addition to these kinds of conditions there can be issues in specific areas of the body, or even the whole body, such as infection, or cancer that can cause nausea. Some medications are known to cause nausea as well. Conditions in specific regions of the body that often lead to nausea include the abdominal region, the pelvic organs, balance centers in the inner ear, as well as spinal or brain fluid. If you are experiencing chronic nausea, or nausea “for no reason”, seek a medical consultation as soon as possible.
