Warm Feeling In Lower Abdomen: Reasons Explained 

Many underlying conditions can cause a warm sensation in the lower abdomen. For your better understanding, several of them are discussed below.

Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease is a disease affecting the digestive system. 

GERD can be caused due to any defect in the lower esophageal sphincter. The lower esophageal sphincter is a circular muscle present between the lower end of the food pipe and the opening of the stomach.


The circular muscle opens intermittently in normal conditions to allow food to enter the stomach from the food pipe. It remains closed at other times to prevent food mixed with stomach acid from flowing back. 

In people with gastroesophageal reflux, the sphincter muscle becomes weak or remains open more frequently. Therefore, acidic stomach contents flow back into the esophagus. It gradually causes damage to the esophagus.

Gastroesophageal reflux can be caused by other factors such as esophageal motor abnormalities, which are related to peristalsis disorders and delayed gastric emptying. 

Gastroesophageal reflux can be one of the causes of unusually warm sensations in the lower belly. In addition to a warm feeling around the lower abdomen, gastroesophageal reflux disease can lead to several other uncomfortable symptoms. 

Some of the symptoms include-

  • Heartburn
  • Chest pain
  • Regurgitation
  • Bitter taste in the mouth 
  • Bad breath
  • Nausea 
  • Vomiting
  • Difficulty in swallowing
  • Dental erosion
  • Asthma
  • Laryngitis
  • Cough

If you have been experiencing some of these symptoms along with a warm or burning feeling in the lower abdomen, it could indicate gastroesophageal reflux disorder. 

Consult your doctor in order to receive the appropriate treatment for your disease.

Peptic Ulcer Disease 

Peptic ulcer disease can also cause a warm sensation in your lower abdomen.

Peptic ulcer disease is a condition in which open sores form in the lining of the stomach, the upper part of the small intestine, or the lower end of the food pipe. 

Stomach acid or pepsin is responsible for the damage. Pepsin is a digestive enzyme that helps in breaking down proteins.


Few factors that can be the cause of peptic ulcers include-

  • Infection due to bacterium Helicobacter pylori
  • Prolonged use of nonsteroidal anti-inflammatory drugs- They are most commonly used to alleviate fever and aches. Ibuprofen and aspirin are common examples
  • Repeated intake of other medications, including steroids, bisphosphonates, and fluorouracil.

Along with a slight burning sensation in the lower abdomen, other symptoms of peptic ulcers are stomach pain, bloating, stomach fullness, heartburn, nausea, and fatty food intolerance.

Some severe symptoms of peptic ulcer include blood in stool, blood in vomit, difficulty in breathing, significant weight loss. These symptoms require emergency medical attention.

Irritable Bowel Syndrome (IBS)

Irritable bowel syndrome is very often associated with causing a slight burning sensation in the lower abdomen. Irritable bowel syndrome is a chronic condition that affects the small and large intestines of the gastrointestinal tract.

Irritable bowel syndrome can make one’s life very uncomfortable. Consult your doctor if you have the symptoms of IBS mentioned above.

In addition to a warm feeling in the lower abdomen, IBS can cause abdominal pain, bloating, constipation, diarrhea, gas, flatulence, and irregular bowel movements.

In different individuals, IBS is associated with various factors. Some of them are mentioned below:

Altered Gut Microbes

Our gut has a variety of microbes such as bacteria and fungi living in it. Most often, they do not cause any harm. However, changes in the normal gut microbiota can result in different problems, including irritable bowel syndrome.

Abnormal Muscular Contractions

In some cases, muscles in the intestine contract more often and with more force. In other cases, it has weaker contractions than usual. This can lead to gas, irregular bowel, and other associated symptoms of IBS.

Increased Sensitivity of Colon or Small Intestine

Poor coordination of signals between the brain and nerves present in the intestine can lead to increased sensitivity of the nerves present in the gastrointestinal tract. 

Infection By Microorganisms

Overgrowth of bacteria such or other microbes can result in infections of the digestive tract. Gastrointestinal infection is a lead factor of IBS.


People with extremely stressful situations often tend to experience more symptoms of IBS. Irritable bowel syndrome can make one’s life very uncomfortable. Consult your doctor if you have the symptoms of IBS mentioned above.



Appendicitis is an inflammation of the appendix. The appendix is a tube-like pouch that projects from the colon in the lower area of the abdomen. It is present on the right side.

Appendicitis is caused by the blockage of the appendix. It can get blocked due to food wastes, cancerous masses, or excessive growth of infectious microorganisms. All of it leads to the inflammation of the appendix.


Appendicitis can be responsible for warm sensations in the lower abdomen. Appendicitis also exhibits other symptoms such as-


Diverticulitis is another reason for causing a warm sensation in the lower midriff. It is a condition where small pouch-like structures called diverticula of your gastrointestinal tract get inflamed or infected.

Infection can be due to the build-up of harmful bacteria around or inside the diverticula.

The urinary system includes the kidneys, ureters, bladder, and urethra. A urinary tract infection can be due to infection in any part of your urinary system.

Endometriosis is a condition of the reproductive system where massive masses of tissue grow in the outer lining of the uterus. The growth of this tissue can spread to other reproductive parts such as the fallopian tubes, ovaries, and lining of the pelvis.

Urinary tract infection can be caused by bacterial infection of the bladder or urethra. In addition, sexually transmitted organisms can also be responsible for causing UTI.

Urinary tract infections are one of the lead causes of kidney damage. Therefore, it is better to get treated if you experience symptoms of UTI.

Pelvic Inflammatory Disease

Pelvic inflammatory disease is a medical condition that affects the reproductive organs of women. 

It is often caused by the spread of sexually transmitted bacteria from the vagina to the uterus, ovaries, or fallopian tubes. 

Pelvic inflammatory disease can cause a slight burning sensation in the lower abdomen. It can cause additional symptoms such as-

  • Fever
  • Pain during intercourse
  • Vaginal discharge 
  • Painful urination
