Discovering blood after a bowel movement can feel alarming. You may wonder: “Is this normal?” or “Should I panic?” At Gastrodoxs.com, we believe everyone deserves clear, friendly guidance. In this post, Dr. Bharat Pothuri, a Houston gastroenterologist, walks you through the key signs that rectal bleeding might be serious—and when it’s OK to stay calm.
“I tell my patients at the Texas Medical Center that not all bleeding is an emergency,” says Dr. Pothuri. “But prompt attention can prevent complications.”
Rectal bleeding means any blood that passes from your anus. You may notice:
Blood appears when tiny vessels in your lower digestive tract break or swell. Common sites include the rectum, anus, or the end of your colon.
Dr. Pothuri notes, “In many Houston clinics, these benign causes account for over half of cases.”
Not all bleeding is painless or mild. Watch for these red flags:
“If you see more than a teaspoon of blood, or if it continues for two days,” says Dr. Pothuri, “it’s time to call your doctor.”
Painless bright red blood in stool can be misleading. You may feel no pain yet pass a noticeable amount of blood. Common causes include:
Because you feel no pain, you might delay care. Dr. Pothuri warns, “Even without discomfort, any recurring bleeding needs evaluation.”
Scenario: You flush and see what looks like a flood of fresh, bright red blood. You feel fine otherwise.
Dr. Pothuri practices at the Houston GI Center near the Texas Medical Center. He adds, “We use the latest endoscopes to spot small lesions early.”
