Experiencing Diarrhea Before My Colonoscopy: Is It Typical?

7/2/2025, 6:50:23 PMMale25-34

I’m a 21-year-old female weighing 210 pounds. Tomorrow morning, I have a colonoscopy scheduled, and so far today, my intake has been solely water, with no food. I haven’t started taking the Suflave yet, as it's not time for me to do so. Just now, I had to rush to the bathroom due to having a loose stool. Is this a common occurrence? This is my first colonoscopy, and I’m curious whether it’s normal to experience diarrhea or very loose stools after only consuming water.

It's understandable to feel anxious about your upcoming colonoscopy, especially if you're experiencing changes in your bowel movements. Having loose stools or diarrhea after consuming only water is not uncommon as your body prepares for the procedure.

Before a colonoscopy, many people undergo a dietary restriction, which typically includes a clear liquid diet. Drinking only water, especially in conjunction with the preparation medications you will take later, can lead to increased urgency and looser stools. Your gastrointestinal system is reacting to the reduction in food intake, which can result in these symptoms.

Next Steps:

  1. Stay Hydrated: Continue to drink clear fluids like water, broth, or electrolyte drinks. This helps prevent dehydration as your body eliminates waste.

  2. Monitor Symptoms: Pay attention to your bowel habits and any accompanying symptoms, like abdominal pain, bloating, or significant discomfort. Mild loose stools are normal, but if you notice severe pain or any distress, it’s best to pause and reassess.

  3. Prepare for Suflave: Once it’s time for your scheduled preparation with the Suflave (or other prescribed laxatives), follow the instructions carefully. This preparation is meant to ensure your colon is sufficiently clear for the colonoscopy, and it's typical to see increased bowel activity after taking these medications.

  4. Stay Calm: It's perfectly normal to feel some anxiety about the procedure—take deep breaths and remind yourself that this preparation is vital for the best possible outcomes.

If anything unusual arises during this preparation or if severe diarrhea persists beyond what you expect, reach out for further guidance. You're doing well in preparing, and soon you'll have valuable insights from your colonoscopy.

Hard Bump Behind My Ear

I have recently noticed a hard bump or structure located behind my right ear. Although I observed that it was larger than the one behind my left ear some time ago, I did not give it much thought. However, it now seems to have increased in size. Until recently, I hadn’t experienced any discomfort, but I am currently feeling a dull ache in that area. I ruled out mastoiditis since there is no swelling, tenderness, or redness present. I have a question: I’m a 25-year-old female. If bone growth typically ceases at this age or earlier, how is it possible that this bony structure has continued to enlarge? What could it actually be? Additionally, I suffer from TMJ on the right side and deal with sinusitis on that same side as well. During episodes of sinusitis, I experience pain throughout the entire right side of my face.

I’m a 25-year-old female currently taking Zoloft, prenatal vitamins, and birth control. Recently, I experienced a wasp sting after quite some time, and I can't recall my previous reactions to such stings. I'm curious if this level of reaction is typical. The area itches considerably and is swollen to the extent that it feels firm.

Overwhelmed by an Intensified Sense of Smell

I am a 47-year-old woman, do not smoke, drink occasionally, and take no medication. Throughout my life, I've always had a keen sense of smell, but lately, it feels like it has intensified to an unpleasant degree. I detect foul odors in various settings—my workplace, specific areas within my home, my vehicle, and even in the homes of others. Generally, these odors go unnoticed by people around me, though on rare occasions, one or two individuals can sense what I'm perceiving. I don't believe these odors are figments of my imagination. They do not surround me everywhere I go, yet when they are present, I consistently recognize them. For instance, one of my cars has a distinctly musty odor that only one other person has acknowledged, while our other car remains completely odor-free. Only certain locations consistently exhibit these unpleasant scents. It's plausible that I'm simply more sensitive to smells than others. I suspect that these particular spaces might have undergone water damage or dealt with rodent issues in the past; however, if that is the case, those problems are likely resolved and the odors remain undetectable to most. The presence of these smells causes me significant discomfort and a feeling of unease. Even neutral or mild scents can provoke an unsettling reaction. Although I've dealt with this to some extent throughout my life, the intensity of my reactions has increased considerably. It's curious to reflect on my college days spent in some questionable, older residences where I didn't seem to mind the scents as much, even if they weren’t always pleasant. I genuinely wish to find a way to lessen my sensitivity to these smells or at least diminish the distress they bring. Is there a method to address this heightened olfactory sensitivity, or is it something I must learn to accept? Additionally, could this amplified sense of smell be indicative of an underlying health issue? I can confirm that pregnancy is not a possibility for me.

Seeking Advice About Blood in Stool

Hello everyone, I’m a 19-year-old woman and I recently observed some bright red blood in my stool, roughly the size of a pea. Prior to this incident, I had noticed blood on the toilet paper on several occasions, but I didn’t think much of it at the time, assuming it was just a minor irritation. I have an appointment scheduled with my doctor later this week, but I can’t help but feel anxious about my situation. Interestingly, I didn’t experience any pain during the bleeding and didn’t have any difficulty during bowel movements. From what I understand, issues like hemorrhoids or fissures typically cause discomfort, which adds to my concern about the possibility of a more severe underlying issue. Is it possible for something like hemorrhoids or anal fissures to occur without causing pain? I would be grateful for any insights that might help alleviate my worries until I meet with my physician.
