The following are some of the common causes of right side abdominal pain;

  1. Appendicitis – One of the most common causes for right side abdominal pain is Appendicitis. The Appendix is located near the cecum and up to this day, there is no clear explanation on what is the function of the appendix to our body.

Once there is a blockage in the appendix due to different reasons, appendicitis develops. The infection in the appendix causes pain on the right side of the abdomen.
  2. Gallstones – When the gallbladder is blocked by gallstones, it causes pain on the right side of the abdomen because the bile cannot go out causing the gallbladder to swell.
  3. Cholecystitis – It is an infection of the gallbladder, and if there is an infection, there is also swelling which causes the painful feeling on the right side of the abdomen.
  4. Ectopic pregnancy – This happens when the egg cell implanted on the fallopian tube instead of the uterus. There is little room to accommodate the growing fetus inside the fallopian tube thus as the fetus keeps on growing, it will squeeze the inner lining of the fallopian tube causing pain on the abdominal area.
  5. Ovarian cyst – As the cyst continue to grow inside the ovary, it will crush the inner lining of the ovary and this will cause pain on the abdomen.
  6. Kidney Stone – When a stone is present in the kidneys, it will naturally roll down to the ureter because of how the fluids in the kidneys flow. When the stone passes down the ureter, its size can cause irritation to the lining of the ureter thus causing pain.
