Why Does Chronic Pain Cause Nausea and Vomiting?

Nausea is a feeling of unease or discomfort in the stomach that can come before vomiting. Nausea is a common symptom of various illnesses, including chronic pain. A pain management specialist can help you understand the connection between chronic pain and nausea and how to manage it.


We will explain why chronic pain can cause nausea, what other symptoms you may experience, and possible treatment options.

There is a strong link between chronic pain and nausea. Chronic pain can impact the central nervous system, which controls how our bodies process sensations like hunger, taste, smell, and nausea. Read on to understand why this occurs.

What Is Chronic Nausea and How Does It Occur?

Chronic nausea is when an individual experiences recurrent episodes lasting for weeks, months, or even years. Various medical conditions and environmental factors, including gastrointestinal issues, chronic pain, or certain medications, may cause it.

Common causes of chronic nausea include:

a) Gastrointestinal Issues:

Many gastrointestinal conditions can cause nausea, such as gastritis, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and food poisoning.

b) Chronic Pain:

It is common for individuals with chronic pain to experience nausea due to their condition. This occurs when the body is stressed and releases cortisol, a hormone that can lead to nausea.

c) Peptic Ulcers:

Peptic ulcers occur when the lining of the stomach or small intestine becomes inflamed. This can cause symptoms such as nausea and vomiting.

d) Inflammatory Bowel Disease:

Inflammatory bowel disease is a condition where the lining of the intestines becomes inflamed, resulting in abdominal pain and nausea. This happens because the inflammation can interfere with the normal functioning of the digestive system.

e) Medications:

Some medications, such as antibiotics and chemotherapy drugs, can cause nausea as a side effect. Additionally, some over-the-counter medications cause nausea when taken in large doses.

f) Stress and Anxiety:

Stress and anxiety can cause nausea due to the body’s release of hormones and chemicals.

g) Hormonal Changes:

Rapid hormonal changes, such as those experienced during pregnancy or menopause, can cause nausea. Some forms of birth control can also be responsible for this symptom.

The symptoms of chronic nausea may include:

a) Nausea

b) Vomiting

c) Abdominal Pain and Discomfort

d) Loss of Appetite

e) Fatigue

f) Sweating

g) Dizziness.
