Is It Safe to Undergo Another Colonoscopy Preparation Three Days After an Incomplete Prep?
I am a 39-year-old female, standing at 5 feet 5 inches tall and weighing 155 pounds. My medical history includes Raynaud’s phenomenon, asthma, gastroesophageal reflux disease (GERD) combined with esophagitis, low blood pressure possibly linked to adrenal gland issues or POTS, irritable bowel syndrome (IBS), and elevated IgE levels. Additionally, I am scheduled for an endoscopy at the same time to check for eosinophilic esophagitis (EOE). Recently, I attempted a colonoscopy preparation using a 64-ounce split dose regimen containing 238 grams of MiraLAX and 68.8 grams of senna. Thankfully, I did not experience any nausea, discomfort, or significant drops in blood pressure, as I made sure to maintain proper hydration. However, the bowel prep did not fully clear, resulting in the need to reschedule my procedure for three days later. I am planning to repeat either the Suflave or the MiraLAX/senna preparation. I’m curious if it is safe to proceed with this preparation so soon after the first one or if I should consider rescheduling once more.

It's understandable to be concerned about undergoing another colonoscopy preparation so soon after an incomplete prep. While many patients do successfully complete their bowel prep shortly after a first attempt, several factors need consideration to ensure your safety and comfort.
Main Points:
- It is usually safe to repeat your colonoscopy preparation three days after an incomplete prep.
- Consider your overall health, hydration status, and any specific medical concerns due to your history.
Explanation: A colonoscopy prep is designed to clear your bowels for the procedure. The fact that you didn't experience nausea or significant blood pressure drops is positive. However, inadequate prep can lead to a less effective procedure, so it’s important to ensure that you’re fully cleared this time. Being cautious due to your medical history—including Raynaud’s phenomenon, asthma, GERD, and IBS—is wise, but with appropriate preparation and hydration, many patients do well.
Next Steps:
-
Hydration: Continue to maintain good hydration before and during the prep. This can help mitigate potential fatigue and ensure your blood pressure remains stable.
-
Choose the Right Prep: Between Suflave and MiraLAX/senna, select a prep that you found tolerable in the past (consider taste and ease of use). If unsure, Suflave is often recommended for its effectiveness.
-
Start Early: Begin your prep at the prescribed time, allowing sufficient time for your bowels to clear. Follow all instructions carefully to maximize effectiveness.
-
Monitor Symptoms: Pay attention to how you feel during the prep. If you notice any unusual symptoms (such as extreme fatigue, dizziness, or worsening abdominal pain), pause and evaluate whether to continue.
-
Consult if Needed: If you have any concerns about your specific condition or experience unforeseen symptoms, feel free to reach out to your healthcare provider for advice before proceeding.
Moving forward with your colonoscopy prep seems reasonable given your situation. Following these steps will help ensure everything goes smoothly. Let me know if you need further guidance!

Feeling Anxious: Missing Periods and Other Symptoms
As a teenager, I'm experiencing some concerning health issues. I haven't had my period for the past two months, and when I do experience abdominal cramps, they're brief and infrequent, lasting only a few minutes every few days. Additionally, I've noticed a complete lack of appetite—it's as if I just don't feel hungry at all. I'm constantly fatigued and battling significant feelings of depression. I have not been sexually active, so I'm certain that pregnancy isn't a factor. I'm not on any medications, nor do I consume alcohol or smoke, and my weight has remained stable for several months. Given that potential causes like pregnancy, substance use, and changes in my medications or weight have been ruled out, I am genuinely worried about what might be going on with my health. However, I prefer to keep this to myself for now. If this isn't the appropriate forum for these concerns, I would appreciate a suggestion for where to seek advice.
Seeking Clarity on My Husband's CT Scan Results to Alleviate Weekend Anxiety
I’m reaching out for assistance regarding my husband’s health situation. He is a 37-year-old male, weighing approximately 250 pounds and standing around 5 feet 7 inches tall. His current medications include Effexor and Adderall, and he has been diagnosed with Crohn's Disease and Irritable Bowel Syndrome (IBS). Recently, we received the CT scan results following a previously conducted MRI. During a recent colonoscopy attempt, the procedure could not be finalized due to significant narrowing of the colon. His gastroenterologist has provided us with two options: we could choose to undergo surgery to remove a portion of the colon now, or we might continue with the Remicade treatment to see if it alleviates the narrowing, allowing for a complete colonoscopy later on. The CT scan results indicate: "Redemonstration of circumferential colonic wall thickening at the proximal descending colon extending over a length of 11 cm with pericolonic lymph nodes measuring up to 1.0 x 1.1 cm. These findings in association with an enlarging hypodense mass within the right hepatic lobe segment 7, now measuring 2.3 x 2.7 cm as well as numerous omental nodules measuring up to 1.0 x 1.1 cm, raise concern for primary colonic malignancy with metastases." Given this report, does it imply the possibility of tumors or cancerous growths? I am feeling extremely anxious right now.
Update on Sudden Vision Loss and Concerns
A sudden loss of vision can be alarming, especially when it manifests quickly in one eye. Regarding my mother, who is 52 years old, stands at 5 feet tall, and weighs around 100 pounds: she has a troubled past marked by two overdoses due to meth, but she has been sober for the past seven years. She also struggles with anorexia and orthorexia, dedicating significant time to yoga and exercise, often working out for five hours daily. Among her unconventional health methods, she consumes naturopathic remedies, such as apricot seeds and methylene blue. Approximately seven months ago, my mother developed an all-over itchy rash, which I initially suspected could be measles. Unfortunately, she refused to seek medical attention from a qualified physician. Alongside the rash, she experienced jaw pain, extreme fatigue, inner ear complications, severe headaches, and persistent feelings of malaise. Last Saturday, she suffered a dramatic decline in her vision, losing roughly 80% of it in her left eye. After being taken to the hospital, she underwent a CT scan that excluded the possibility of a stroke. Medical professionals informed her that she had tertiary syphilis and required hospitalization, but she declined and opted for steroid eye drops instead, as she doesn’t trust conventional medicine. I am genuinely concerned about the potential life-threatening nature of syphilis, and I wonder how much time may remain for her without appropriate treatment. Subsequent medical evaluations confirmed the diagnosis of syphilis, identifying it as ocular syphilis. On the first day she started taking doxycycline orally, she went to bed and unexpectedly found herself on the opposite side of her room with no recollection of how she got there. This was followed by five hours of vomiting, along with persistent fogginess and headaches lasting two days thereafter. I fear she may be experiencing seizures when alone and not recalling these episodes. During her time as an addict, she suffered numerous seizures and even set up a camera to keep track of them for her safety. My concerns about the possibility of neurosyphilis are growing. Despite this concern, all she has been prescribed is four weeks of doxycycline, a cortisol steroid, and steroid eye drops, with a follow-up scheduled for August. She is severely fatigued, and her compulsive exercising—driven by OCD—has come to a halt. I have reached out to her doctors, yet none have responded to my inquiries. Am I being overly protective? Should I place my trust in their medical expertise? From my research, I do not grasp why they are not utilizing penicillin desensitization or suggesting further treatment options. Moreover, the doctors assured her that her eyesight would definitely improve, yet there have been no changes after a week. I acknowledge my limitations as a layperson, but based on my findings on syphilis, both ocular and neurological, the treatment plan she has been given seems inadequate. Additionally, given her history as a drug addict, I suspect she may not be receiving the appropriate level of care. She was a victim of sex trafficking around 15 years ago, potentially leading to her current syphilis infection. Her life has been exceedingly challenging, and my greatest fear is that she may pass away just as her condition appears to be improving. Please advise me: should I adopt a more assertive stance and advocate for better care on her behalf, or am I being too alarmist? Thank you for your insights.
Intense Head Jolt Experienced Before Waking
As a 32-year-old man, I want to share a peculiar episode I encountered shortly after consuming two beers the night prior. While resting in bed, teetering between wakefulness and sleep but not dreaming, I abruptly felt a powerful internal jolt similar to a loud thump or spasm within my head. This was immediately followed by a sensation akin to sleep paralysis that lasted for several moments. Although fully aware, I found myself unable to move. This episode lasted roughly 5 to 10 seconds, after which I regained full consciousness and normal physical function. I experienced no issues with speech, weakness, or numbness, and my vision remained clear. The only residual effect was a slight headache, likely attributable to the lack of quality sleep or potential hangover. I am familiar with the feeling of sleep paralysis, having had encounters with it previously, but this particular incident was distinctly more acute, characterized by its sudden and shocking nature, accompanied by that internal noise. It was so distressing that it crossed my mind that I might be experiencing a stroke. Following the episode, my blood pressure read at 130/83. Currently, I have not displayed any neurological symptoms, though I am grappling with lingering feelings of anxiety and fatigue. It’s worth noting that my mother had a stroke a few months back, which may have heightened my concerns about this event. What might have caused this occurrence? Thank you for your insights!
Concerns About White Bumps on Scrotum
Hello everyone, This is my first time posting here. I’ve noticed the presence of small white bumps on my testicles for several years now, although I’m unsure how long exactly. I think they first appeared before I became sexually active. I've undergone STD screening, including both urine and blood tests, for various reasons, all of which returned negative results. The bumps are somewhat similar to pimples in that they can be popped, although I tend to avoid doing so. They are not painful or itchy, but they occasionally increase in size or sink deeper beneath the skin, which is frustrating. Previously, I was on isotretinoin to treat acne on my face, but it didn’t have any effect on these bumps. From my online research, I’ve come across terms like Fordyce spots and sebaceous cysts, but I’m still unclear about what these actually mean in terms of treatment or necessary action. I am eager to eliminate these bumps or at least gain a better understanding of their nature. Perhaps switching to more breathable underwear or applying a skincare regimen to my scrotum could help? If you need any more details from me, please let me know. Thanks for your help!
