Men and people of white ethnicity tend to develop abdominal aortic aneurysms more often.


The aorta in the lower abdomen may inflame over time without any symptoms. Some people will experience back pain and mild chronic pain deep in the abdomen.

Mild diverticulitis can be left untreated but requires close monitoring. Some medications like amoxicillin can be administered to improve the condition. If the pain is persistent, topical pain killers will help.

People with acute symptoms of diverticulitis are advised to consume food products with low fiber content. A lot of fluids are also not encouraged during the recovery period. Your doctor will advise on the best treatment approach.

Ovarian cysts

It is common to have cysts in different body parts. A hard lump on the wrist for example is usually as a result of a ganglion cyst. Women have two ovaries, each located on either side of the lower abdomen. Cysts occurring on the ovaries can lead to formation of left and right lump in lower abdomen.


  • Follicular cysts – form when follicles in the Fallopian tubes fail to rupture in order to release a mature egg during menstruation.
  • Corpus letum cysts – develop when fluid collects inside follicle after a mature egg is released into the fallopian tubes for fertilization.
  • Endometriomas – develop when some endometrial tissue grows outside the womb and partly attaches to the womb.
  • Dermoid cysts – develop from embryonic cells.
  • Cystadenomas – form on a woman’s ovary. They are filled with fluid.


  • Pain in the region around the pelvis
  • Bloats
  • Feeling full even before eating

Diagnosis can be done through pregnancy test or use of ultrasound imaging. For treatment, birth control pills might be prescribed. The cysts can also be left to resolve on their own. This however requires close monitoring. Large cysts that do not resolve can be removed surgically.
