16 Possible Causes of Lower Right Abdominal Pain

The abdomen, also called belly, is the part of your body running from below the breastbone down to the upper area of the pelvis. This area contains many vital organs, including your kidney, intestine, liver, and gallbladder. If any of these organs become irritated or infected, they commonly cause symptoms like pain and discomfort.

When experiencing lower right abdominal pain, most people conclude that they have appendicitis. But there are numerous other causes that also require immediate medical attention. The right ovary of women and also part of the colon are located in this region. Although most abdominal pains disappear after a few days of rest, it is essential to know the underlying cause to treat the problem accordingly.

If you are experiencing persistent pain or discomfort, make an appointment with your doctor so they can evaluate your symptoms and make a proper diagnosis.  Seek medical attention if you have fever, bloody stools, nausea and vomiting, yellowish skin or jaundice, swelling of the abdomen, tenderness when touching the abdomen, and pressure or pain in your chest.

Lower Right Abdominal Pain

What are the Causes of Lower Right Abdominal Pain?

Below are the possible causes of pain in the lower right abdomen.

1. Appendicitis

The common cause of pain in the lower right abdomen is appendicitis. This occurs when the appendix, which is a finger-shaped pouch that doesn’t seem to have a certain purpose, becomes irritated or inflamed. Pain usually starts from the navel area, and discomfort increases as inflammation worsen.

Other symptoms of appendicitis include loss of appetite, nausea, and vomiting, diarrhea or constipation, abdominal bloating, and pain that worsen if you walk, cough, or make jarring movements.

See a doctor immediately as this condition can cause serious complications, such as a ruptured appendix and abscess or infection.

2. Intestinal Gas

Air in the digestive tract or intestinal gas often goes unnoticed until we pass it rectally (flatulence) or burp. Trapped gas in the intestines may result in abdominal pain for a short period of time. Although all people pass gas many times a day, excessive gas may indicate a digestive problem.

Excess upper intestinal gas can be caused by chewing gum, swallowing air, smoking, and overeating. On the other hand, excess lower intestinal gas can result from eating high amounts of certain foods, by a disruption in the bacteria in the intestines, or by inability to digest certain foods fully.

Common foods that cause excess gas include lentils, beans, cruciferous vegetables, fructose, dairy products, carbonated beverages, and bran.

3. Hernia

A hernia occurs when an internal organ or a body part pushes through muscle or tissue that keeps it in place. There are many types of hernias that can happen in the abdominal area. All types can cause discomfort or pain.

Other symptoms include feeling constipated or full, bulging or swelling at the side, a dull ache, and pain while lifting, coughing, laughing, or straining.

The most common type of hernia is inguinal hernia. This occurs when contents of the abdomen, such as part of the small intestine or fat, protrudes or sticks out through a weak spot in the abdominal wall. Since it cannot improve on its own and can lead to serious complications, the best treatment for it is a surgical procedure.

4. Indigestion

Also called an upset stomach or dyspepsia, indigestion develops after drinking or eating certain foods. Anxiety, smoking, and certain antibiotics may also cause indigestion.

Although pain commonly occurs in the upper abdomen, it can also be felt in the lower area. Some of the symptoms that you may experience include feeling full during a meal, discomfort in the abdominal area, burning sensation, nausea, and bloating.

Generally, mild indigestion is nothing to fret about. See your doctor if pain or discomfort persists, especially if accompanied by tarry stools, repeated vomiting, loss of appetite, weakness or fatigue, trouble swallowing, and unintentional weight loss.

5. Kidney Stones

Kidney stones, also called nephrolithiasis and renal lithiasis, are hard deposits made of salts and minerals that form in the kidneys.

People do not feel any discomfort or pain until the stones start to move or pass into the tube that connects the kidney to the bladder. When this happens, you may experience severe pain in your side or back and throughout your groin and lower abdomen.

The location and intensity of the pain may change as the stone moves and shifts through the urinary tract. Some symptoms that may come with it include painful urination, nausea or vomiting, urine that smells bad or cloudy, red or brown urine, frequent urination, and strong urge to pee many times.

6. Kidney Infection

The most common cause of kidney infections is bacteria that enter the urinary tract through the urethra, the tube that carries urine from the body.

One or both kidneys could be infected, and this condition requires prompt medical attention. Without proper treatment, the bacteria can spread to your bloodstream and may cause severe complications.

In addition to feeling pain in the lower abdomen, other symptoms of kidney infection include nausea, vomiting, chills, fever, frequent urination, burning or pain when urinating, and feeling the need to urinate frequently.

7. Diverticulitis

Diverticula are bulging pouches that can develop in the lining of the digestive tract, most often in the lower area of the colon. These are common among people who are over 40. But when one or more of these small pouches become infected or inflamed, this condition is called diverticulitis.

Common symptoms of diverticulitis include constant pain in the abdominal area, fever, nausea and vomiting, abdominal tenderness, and diarrhea or constipation. Although mild diverticulitis may be treated at home, surgery may be required in cases of complicated diverticulitis.

8. Irritable Bowel Syndrome

The main cause of irritable bowel syndrome isn’t known, but several factors can contribute to its development, such as inflammation in the intestines, muscle contractions, and abnormalities in the nerves in the digestive tract. Stress, food, and hormones can also trigger the symptoms of IBS.

Besides abdominal pain, you may also experience bloating, cramping, constipation or diarrhea, excess gas, and mucus in your stools. More-serious symptoms include unexplained vomiting, weight loss, difficulty swallowing, rectal bleeding, iron deficiency anemia, and pain that isn’t relieved by a bowel movement or passing gas.

See a doctor if you experience any of the symptoms as it may indicate a more severe condition, such as colon cancer.

9. Inflammatory Bowel Disease

Inflammatory bowel diseases are disorders that involve chronic inflammation of the digestive system. Even though the exact cause is still unknown, stress and diet were suspected to aggravate IBD. Factors that may also increase one’s risk of developing IBD are family history, use of nonsteroidal anti-inflammatory medications, and smoking.

Types of inflammatory bowel disease include Chron’s disease and ulcerative colitis. Both conditions may involve abdominal pain, severe diarrhea, weight loss, and fatigue.

Other symptoms that are both common to ulcerative colitis and Chron’s disease are cramping, fever, and blood in stools. If left untreated, it can lead to life-threatening complications.

10. Testicular Torsion

One of the causes of lower right abdominal pain in men, testicular torsion occurs when the testicle rotates and twists the spermatic cord. This will reduce blood circulation, causing severe pain and swelling. Although it can happen at any age, it is most common between ages 12 and 16. This condition requires immediate surgery. If treated right away, the testicle can be saved.

In addition to abdominal pain, other signs and symptoms of testicular torsion include painful urination, severe pain in the scrotum, swelling of the scrotum, fever, nausea, and vomiting. You may also notice that a testicle is at an unusual angle or higher than normal.

11. Endometriosis

Endometriosis could also cause lower right abdominal pain in women. It is a painful disorder that occurs when the endometrium, tissue that lines the inside of the uterus, develops outside the uterus. This condition commonly involves the fallopian tubes, ovaries, and the tissue lining of the pelvis. In rare cases, it may spread beyond pelvic organs.

The first symptom of endometriosis is pain in the pelvic area, often linked to menstrual period. Women with this condition reported that their menstrual pain is far worse than normal. Other symptoms of endometriosis include excessive bleeding, pain with intercourse, pain with urination or bowel movements, and infertility.

12. Ovarian Torsion

Also known as adnexal torsion, ovarian torsion happens when an ovary or fallopian tube becomes twisted, cutting off the blood supply to the organ. One of the possible causes of lower right abdominal pain, its other symptoms includes pain during sex, irregular periods, feeling full during a meal, nausea, and vomiting. Without prompt treatment, it can lead to loss of an ovary.

Although it is unclear how this condition occurs, women are more likely to get ovarian torsion if they developed ovarian cysts. Other factors that can increase one’s risk of experiencing it are being pregnant, having a long ovarian ligament, polycystic ovarian syndrome, have had a tubal ligation, and undergoing hormonal treatments.

13. Pelvic Inflammatory Disease

An infection of the female reproductive organs, pelvic inflammatory disease happens when sexually transmitted bacteria enters the vagina and spreads to uterus, fallopian tubes, or ovaries. PID doesn’t always show signs and symptoms, so the condition might be detected later if you experience severe pelvic pain or if you have trouble getting pregnant.

Symptoms of PID include pain in the lower abdomen, heavy vaginal discharge with foul odor, bleeding or pain during intercourse, painful urination, and abnormal uterine bleeding. If these signs occur, avoid having sex and consult your doctor.

14. Ovarian Cyst

Another possible cause of lower right abdominal pain is ovarian cyst, which is a fluid-filled pocket or sac in or on the surface of an ovary. Many women develop ovarian cysts, but most are harmless, don’t cause any discomfort or pain, and go away on their own. However, large ovarian cysts can cause bloating, heaviness or fullness in the abdomen, and dull or sharp ache in the lower abdomen.

Visit your physician immediately if the symptoms are accompanied by rapid breathing, fever, weakness, sudden or severe abdominal pain, clammy and cold skin, and vomiting. Infrequent complications associated with this condition are rupture and ovarian torsion.

15. Ectopic Pregnancy

An ectopic pregnancy happens when a fertilized egg attaches and develops outside the uterus. This pregnancy cannot continue normally as the embryo is not able to survive. If left untreated, the growing tissue may lead to life-threatening bleeding.

Women experiencing ectopic pregnancy may have the early symptoms of pregnancy, such as breast tenderness, missed period, and nausea. However, it can’t proceed as normal, and symptoms will increase as the fertilized egg develops in the improper area.

Seek medical attention if you experience the signs of ectopic pregnancy along with shoulder pain, severe abdominal pain, fainting or lightheadedness, and vaginal bleeding.

16. Colon Cancer

A type of cancer that starts in the ovaries, ovarian cancer is often unnoticed until it has spread within the abdomen and pelvis. At this stage, it is frequently fatal and more difficult to treat.

Chemotherapy and surgery are commonly used to treat this type of cancer. Early-stage ovarian cancer doesn’t always show symptoms, but the signs of advanced-stage ovarian cancer are often mistaken for other common benign conditions.

When symptoms occur, these may include abdominal bloating or swelling, weight loss, a frequent need to urinate, discomfort or pain in the pelvis area, and quickly feeling full during a meal.  If you experience any symptoms that worry you, visit your doctor for proper diagnosis and prompt treatment.

Final Word

Most cases of lower right abdominal pain are nothing to worry about. Mild conditions, such as indigestion and intestinal gas, can be treated at home with natural remedies. But if the pain lasts for more than a few days, make sure that you consult your doctor immediately.
