What Causes Pain on the Right Side of the Stomach?

Stomach Pain

Pain on the right side of the stomach can be caused by a variety of underlying conditions and factors. The location and characteristics of the pain, as well as any accompanying symptoms, can help determine the potential cause. Here are some common causes of right-sided abdominal pain:

  1. Appendicitis: Appendicitis is the inflammation of the appendix, a small organ located in the lower right abdomen. This condition often starts with vague abdominal pain that can intensify and migrate to the lower right side. Other symptoms may include fever, nausea, vomiting, and loss of appetite. Appendicitis is a medical emergency and requires immediate attention.
  2. Gallstones: Gallstones are solid particles that can form in the gallbladder, an organ located on the right side of the abdomen. When a gallstone blocks the bile duct, it can cause sharp, severe pain in the upper right abdomen, known as biliary colic. This pain may radiate to the back or right shoulder and is typically triggered by fatty or greasy foods.
  3. Gallbladder Inflammation (Cholecystitis): Inflammation of the gallbladder can result from gallstones blocking the bile ducts or from infection. This can cause constant pain in the upper right abdomen, along with fever, nausea, and vomiting.
  4. Liver Conditions: Liver conditions, such as hepatitis or liver abscess, can cause right-sided abdominal pain. The pain may be accompanied by jaundice (yellowing of the skin and eyes), fatigue, and other liver-related symptoms.
  5. Right Kidney Issues: Kidney problems, such as kidney stones, infections, or kidney infections (pyelonephritis), can cause pain on the right side of the abdomen or back. The pain may be accompanied by urinary symptoms like frequent urination, pain while urinating, or blood in the urine.
  6. Muscle Strain: Strained or pulled muscles in the abdominal wall, especially on the right side, can cause localized pain. This pain is typically worsened with movement and may result from physical activity or injury.
  7. Digestive Disorders: Conditions like irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), or constipation can cause discomfort and pain in the right lower abdomen. These conditions may also be associated with changes in bowel habits, such as diarrhea or constipation.
  8. Hernia: An inguinal hernia or an incisional hernia in the lower abdomen can cause discomfort or pain on the right side when a portion of the intestine pushes through a weakened abdominal wall.
  9. Ovarian Issues (in females): In females, pain on the right side of the lower abdomen can be related to issues with the right ovary, such as ovarian cysts or ovarian torsion. These conditions may be accompanied by pelvic pain and changes in menstrual cycles.
  10. Gas or Indigestion: Simple gas or indigestion can cause temporary discomfort and a sensation of bloating or fullness on the right side of the abdomen.

If you or someone you know experiences persistent or severe right-sided abdominal pain, especially if accompanied by other concerning symptoms like fever, vomiting, or jaundice, it’s essential to seek medical evaluation promptly. The specific cause of the pain will require diagnosis by a healthcare professional, who can recommend appropriate treatment or further investigations, such as imaging or blood tests, to determine the underlying condition.
