[45M] With blood in stool and lower left abdominal pain

What might be happening

Based on the information you've provided, possible diagnoses include:

• Hemorrhoids: Hemorrhoids are swollen veins in your lower rectum. Internal hemorrhoids are usually painless, but tend to bleed. You've mentioned a past experience with internal hemorrhoids, which could explain the blood in your stool.

  • Treatment typically involves over-the-counter creams or suppositories, a high-fiber diet, and drinking plenty of fluids. In some cases, a medical procedure to remove the hemorrhoid may be necessary.

• Diverticular disease: This condition involves small pouches, or diverticula, that bulge outward through weak spots in the colon. Diverticulosis can cause mild cramps, bloating or constipation, and diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits.

  • Mild diverticulitis can be treated with rest, changes in your diet and antibiotics. Severe or recurring diverticulitis may require surgery.

• Colorectal cancer: Although less likely, given your age and the presence of blood in your stool, it's important to rule out colorectal cancer. The risk of colorectal cancer increases with age, and it's most often found in people 50 and older.

  • Treatment typically involves surgery to remove the cancer. Other treatments, such as radiation therapy and drug treatments, might be recommended based on the stage of the cancer.

What you can do

1. Consult a doctor: Given your symptoms and medical history, it's important to consult a healthcare professional who can provide a formal assessment and order relevant tests if necessary.

2. Monitor your symptoms: Keep track of your symptoms and make note of any changes or patterns. This information can be helpful to your healthcare provider.

3. Maintain a healthy diet: Eating a diet high in fiber can help prevent constipation and promote healthy bowel movements. This can be particularly helpful if you have hemorrhoids or diverticular disease.

What you should look out for

Reasons to seek immediate medical attention:

• If you notice a significant increase in the amount of blood in your stool
• If your abdominal pain becomes severe or is accompanied by fever or nausea
• If you experience a marked change in your bowel habits
