What does it mean if I feel a horizontal, elongated lump above my belly button, and what should I do about it?
Under normal circumstances, a horizontal strip felt above the navel may be caused by abdominal muscles, intestinal fecal masses, abdominal wall varicose veins, pancreatic pseudocysts, rectus sheath hematoma, or other reasons. Depending on the specific situation, improvements can be achieved through general management, medication, or surgical treatment. A detailed analysis is as follows:

1. Abdominal Muscles
The rectus abdominis muscles lie on either side of the midline of the abdominal wall. In individuals with a lean body type, muscle contours are clearly visible and may feel like a horizontal strip upon touch. No special treatment is required. Maintain a balanced diet to improve physical condition and avoid excessive dieting that could lead to muscle atrophy.
2. Intestinal Fecal Mass
Chronic constipation can cause feces to accumulate in the transverse colon, forming a hard, elongated mass that may be movable upon palpation. Increase intake of dietary fiber-rich fruits and vegetables, maintain daily water intake of 1500–2000 mL, and develop regular bowel habits.
3. Abdominal Wall Varicose Veins
Increased portal venous pressure leads to dilated and tortuous abdominal wall veins, forming cord-like bulges above the umbilicus. Actively treat the underlying disease, take propranolol tablets, spironolactone tablets, and furosemide tablets as prescribed, and avoid abdominal compression.
4. Pancreatic Pseudocyst
Following pancreatitis, leaked pancreatic fluid may become encapsulated and form a cyst located deep above the umbilicus. The cyst typically feels elongated and firm. Avoid greasy foods, take omeprazole enteric-coated capsules and somatostatin injection as directed, and consider cyst drainage if necessary.
5. Rectus Sheath Hematoma
Trauma or intense physical activity may rupture blood vessels in the rectus abdominis muscle, leading to blood accumulation and hematoma formation. The area feels elongated and tender upon touch. Rest in bed and avoid strenuous activities. Take tranexamic acid tablets and Yunnan Baiyao capsules as prescribed. Surgical evacuation may be needed if the hematoma is large.
Maintain regular eating habits and prevent constipation in daily life; avoid abdominal trauma and excessive straining. Pay prompt attention to symptoms such as abdominal pain or bloating. If the elongated mass persists or is accompanied by fever or unexplained weight loss, seek medical evaluation promptly for accurate diagnosis.
