Why Do I Feel a Lump in My Lower Abdomen When Lying Down?

Feeling a lump in your lower abdomen while lying down can be attributed to several non-serious reasons. One common cause is a lipoma, which is a benign, soft fatty deposit that may be palpable when you are supine and your abdominal muscles are relaxed. If you’ve had previous abdominal surgery, such as a cesarean delivery, scar tissue or a small incisional hernia can also be present; these may not be noticeable when you’re active but become more apparent in certain positions. Moreover, natural variations in the distribution of fat and tissues in the abdominal wall can create the sensation of a lump when you’re lying down. While these findings are often benign, it’s important to have any new or concerning lump evaluated by a healthcare provider to rule out other causes and ensure appropriate management if needed.
