Changes in Bowel Movements: Causes and Concerns - Gastroenterology and Hepatology

Bowel issues

Hello Doctor, I would like to ask you about my situation.
Previously, I would have a bowel movement about 1 to 2 times a day with normal color.
However, for the past week, my stool has been consistently dark green, and the frequency has increased to 3 to 4 times a day, sometimes even 3 times in one morning.
The consistency is somewhat loose but not watery, and I do not experience significant abdominal cramping or urgency.
Since November 21, I have been taking progesterone medication for gynecological issues, along with fish oil, B vitamins, vitamin C, DIM, vitamin D3, calcium, magnesium, zinc, probiotics, and blueberry supplements daily.
I also consume a fair amount of vegetables, but only a small amount of dark green vegetables like broccoli.
I would like to know if this could be related to my diet or medications.
However, since I have been on these medications and diet for a while and my bowel habits were normal initially, the unusual symptoms have only started this past week.
Could this indicate a gastrointestinal issue?

If there is no improvement, please consult a gastroenterologist.

More Info

Changes in bowel movements can be concerning, especially when they deviate from your normal patterns. In your case, you've noticed an increase in the frequency of bowel movements, with a change in color to a dark green and a somewhat loose consistency. These changes can be attributed to several factors, including dietary influences, medication effects, and underlying gastrointestinal issues.

Firstly, let's consider the dietary aspect. The consumption of certain foods can significantly affect the color and consistency of your stool. Dark green stools can often result from eating a large amount of green vegetables, particularly those high in chlorophyll, such as spinach or kale. However, you mentioned that your intake of deep green vegetables has been limited to broccoli. It's also worth noting that foods rich in iron or certain food colorings can lead to darker stools. If you've recently increased your intake of foods or supplements that contain iron, this could also be a contributing factor.

Regarding the medications you are taking, hormonal treatments like the one you mentioned (likely a form of progestin) can have various gastrointestinal side effects. Some individuals may experience changes in bowel habits, including increased frequency or changes in stool consistency. Additionally, the combination of supplements you are taking, including fish oil and probiotics, can also influence bowel movements. Fish oil, for instance, can have a mild laxative effect in some individuals, leading to more frequent bowel movements.

The increase in bowel movement frequency from 1-2 times a day to 3-4 times a day, especially if it is accompanied by a change in stool consistency, could also suggest a mild gastrointestinal upset. This could be due to stress, dietary changes, or even an infection. Stress and anxiety can significantly impact gut motility, leading to changes in bowel habits. If you are experiencing increased stress or anxiety, this could be a contributing factor.

While the absence of abdominal pain or a sense of urgency is reassuring, it’s essential to remain vigilant. If the changes in your bowel habits persist, or if you start to experience additional symptoms such as abdominal pain, blood in your stool, or significant weight loss, it would be prudent to consult a healthcare professional for further evaluation. They may recommend tests such as stool analysis or imaging studies to rule out any underlying gastrointestinal conditions.

In summary, the changes you are experiencing in your bowel movements could likely be attributed to a combination of dietary factors, the effects of your medications, and possibly stress. Monitoring your symptoms and maintaining open communication with your healthcare provider is crucial. If the changes continue or worsen, seeking medical advice would be the best course of action to ensure your gastrointestinal health is properly assessed.
