Common Causes

Most often, a lump in the abdomen is caused by a hernia. An abdominal hernia occurs when there is an area where the muscles are weak. This allows the internal organs to bulge through the abdominal wall. A hernia may not appear until after you strain, lift something heavy, or have a prolonged period of coughing.

There are several types of hernias, based on where they occur:

• Inguinal hernia appears as a bulge in the groin or scrotum. This type is more common in men than women.
• Incisional hernia can occur through a scar if you have had abdominal surgery.
• Umbilical hernia appears as a bulge around the belly button. It occurs when the muscle around the navel doesn't close completely.

Other causes of the lump in the abdominal wall include:

• Hematoma (collection of blood under the skin after trauma)
• Lymph nodes
• Lipoma (collection of fatty tissue under the skin)
• Undescended testicle
• Tumor of the skin or muscles

Home Care

Seek appropriate care for chronic cough or constipation if you have a hernia. Straining associated with these conditions causes the intestines to bulge further into the hernia.
