Change in Bowel Habits: Key Blood Markers to Consider
Understand the blood markers to check when experiencing a change in bowel habits and when to consult a doctor.
A change in bowel habits can be concerning, especially if it persists for a while. This change can manifest as diarrhea, constipation, or a change in the consistency or frequency of stools. Identifying the underlying cause is crucial, and certain blood markers can provide valuable insights.
What are bowel habits?
Bowel habits refer to the regular pattern of bowel movements, including their frequency, consistency, and ease of passage. Normal bowel habits can vary widely from person to person, but a significant change could indicate an underlying issue. Changes might include increased frequency (diarrhea), decreased frequency (constipation), or changes in stool consistency.
Blood markers to check
When experiencing a change in bowel habits, checking specific blood markers can help identify potential causes:
C-reactive protein (CRP): This marker indicates inflammation in the body. Elevated CRP levels can suggest inflammation in the intestines, which may occur in conditions like inflammatory bowel disease (IBD).
Erythrocyte sedimentation rate (ESR): Like CRP, an elevated ESR can indicate inflammation. It is often used alongside CRP to assess inflammatory conditions.
Complete blood count (CBC): This test measures various components of the blood, including white blood cells, red blood cells, and platelets. Abnormalities in these counts can indicate infections, anemia, or other conditions affecting bowel habits.
Liver function tests (LFTs): These tests assess the health of the liver. Liver issues can sometimes affect digestion and bowel movements.
Thyroid function tests: Since thyroid hormones regulate metabolism, abnormal thyroid function can lead to changes in bowel habits, such as constipation or diarrhea.
Why these markers matter
Blood markers provide a snapshot of what's happening inside the body. For example, elevated CRP and ESR levels can point to inflammatory processes, which are common in conditions affecting bowel habits. A CBC can reveal infections or anemia, which might be causing or contributing to the symptoms. Understanding these markers helps in diagnosing and managing the underlying cause effectively.
When to see a doctor
If you experience a persistent change in bowel habits, it's important to consult a healthcare provider. This is especially true if you notice blood in your stool, experience severe abdominal pain, or have unexplained weight loss. These symptoms might indicate a more serious condition that requires medical evaluation.
