Concerns Regarding Colon Cancer and Weight Loss Journey
I am a 39-year-old Caucasian male, weighing 112 kg and standing 173 cm tall. Since February, I've experienced a persistent dull discomfort in my left upper quadrant, akin to cramping that ebbs and flows. Initially, I attributed my intermittent loose stools to a poor diet. After consulting my general practitioner, I was referred to a gastroenterologist and scheduled for a CT scan to evaluate my bowels, kidneys, and spleen. The scan revealed a 3 mm lung nodule but indicated no other significant findings. Soon after, I began using Wegovy to assist in weight loss, starting from 126 kg in February. Over the subsequent weeks, I consistently lost about 1 kg weekly by maintaining a healthier diet and committing to the gym, reaching 118 kg by April. In late June, during my consultation with the gastroenterologist, he suggested that I likely had inflammatory bowel disease (IBD) or possibly a mix of irritable bowel syndrome and another gastrointestinal issue. He recommended that I follow a low-FODMAP diet and ordered blood and stool tests, which unfortunately showed no significant issues. By this appointment in June, my weight had dropped to 112 kg, and I discontinued Wegovy around the same time. I have managed to maintain my weight within this range since then. Although I requested a colonoscopy, the gastroenterologist assessed it as non-urgent, and my referral through the public health system is scheduled for sometime between now and the end of September. Recently, I underwent a chest CT scan due to ongoing swelling in lymph nodes in my armpit and neck. This scan indicated that the lung nodule had increased to 4 mm, while the upper abdomen appeared normal. I consulted another gastroenterologist via phone, a friend of a friend, who agrees with my original doctor's assessment, suggesting that there are no immediate red flags that warrant concern at this stage. My main concern is whether waiting another month or two for the colonoscopy could adversely affect my prognosis if colon cancer were present. Unfortunately, the gastroenterologist believes an urgent scope is unnecessary, and even seeking another specialist would likely yield a similar delay due to the public healthcare system's timelines. Meanwhile, I continue to experience that occasional dull ache. While my stool patterns are variable, they have shown slight improvement after altering my diet. I recognize that my weight loss from February to mid-July can be attributed to Wegovy and the low-FODMAP diet; however, I have always found losing weight challenging, and it seems to have come off more easily than expected, even after stopping Wegovy. Although a CT scan isn’t the definitive method for diagnosing colon cancer, if it were causing my symptoms, wouldn't it have likely been detected? Additionally, if cancer had progressed, wouldn’t the scan have revealed something?

Thank you for sharing your situation so thoroughly—it's clear that you're experiencing significant concerns about your health, especially regarding your symptoms, weight loss journey, and the possible connection to colon cancer. I'll address your main concerns and provide some actionable guidance.
Key Points
- Your symptoms and weight loss journey are significant and warrant close monitoring.
- The increase in the size of the lung nodule, while concerning, may not necessarily indicate an underlying urgent issue.
- Understanding the timeline for your colonoscopy and potential implications is essential.
Explanation
You've been through a detailed diagnostic process already, with a CT scan revealing no immediate red flags in your abdomen, even with the ongoing dull discomfort in your left upper quadrant and variable stool patterns. It’s common for symptoms like these to be caused by gastrointestinal issues other than cancer, such as inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS).
While it's true that waiting for a colonoscopy can feel daunting, the assessments made by your gastroenterologists suggest that immediate concerns for colon cancer are low at this time. The CT scan’s ability to show structures related to colon cancer is limited; while it can reveal large tumors or advanced disease, early-stage cancers might not be detected.
Actionable Next Steps
-
Monitor Symptoms Closely: Keep a daily journal of your symptoms, noting the intensity and frequency of your discomfort, any changes in your stool patterns, and related dietary impacts. This information will be useful for your healthcare provider when evaluating your ongoing concerns.
-
Follow the Low-FODMAP Diet: Continue with the low-FODMAP diet as advised by your gastroenterologist, as it has already shown slight improvement in your stool patterns. This diet minimizes certain types of carbohydrates that can cause digestive discomfort.
-
Stay Engaged with Healthcare Providers: Although you’ve been advised that the colonoscopy is non-urgent, do not hesitate to communicate any new or worsening symptoms to your gastroenterologist. Be proactive in following up on your slated appointments and tests.
-
Manage Weight Healthily: Given that you've noticed weight loss is becoming more manageable, consider focusing on long-term, sustainable changes in your diet and physical activity that suit your lifestyle.
-
Seek a Second Opinion if Needed: If your symptoms become more concerning or if you continue to feel anxious about the timing of the colonoscopy, don’t hesitate to seek a second opinion from a different gastroenterologist if you have access and resources for it.
-
Mental Well-being: Navigating health concerns can be stressful. Consider speaking to a counselor, therapist, or support group to help manage anxiety or stress related to your condition.
Conclusion
You are making significant efforts to improve your health, and it’s important to continue this path while monitoring your symptoms closely. The steps outlined above can help you feel more in control while awaiting your colonoscopy. Remember, your health is a partnership with your care providers, so advocate for yourself when necessary. If you have further questions or need support, feel free to reach out.

Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.

Navigating Ear Infections While Traveling in Thailand
**Age:** 23 **Height:** 6'3" **Weight:** 88 kg **Medication Taken:** 1000mg Bactoclav - Amoxicillin with Potassium Clavulanate, along with pain relief and antihistamines. **Summary:** I’m hesitant to consult a doctor overseas only to receive a prescription for the same antibiotics available at a local pharmacy for a fraction of the price. What strategies can I employ to effectively manage this persistent ear infection? Am I being too hasty in my expectations? I have a long history of ear infections, often triggered by exposure to water or any activity impacting my ears. I regularly use a specialized oil before showering to prevent water from entering my ears. While backpacking in Thailand, I've developed a particularly severe ear infection over the last several days. Initially, a course of 500mg amoxicillin seemed effective, but significantly, just yesterday my condition took a downturn, shifting from nearly healed to painfully inflamed. Now, my ear is not only swollen but also incredibly sore. In an attempt to combat this, I’ve been taking 1000mg Bactoclav - Amoxicillin and Potassium Clavulanate, having consumed seven tablets in the last two days; unfortunately, there's been no noticeable improvement. I’m reluctant to seek medical attention, fearing I would be prescribed the same medication I could acquire from a pharmacy, albeit at a much higher cost. Yet, I’m also starting to question the efficacy of the pharmacy’s medication. I’ve only recently begun the stronger treatment since my symptoms returned. Any advice would be greatly valued! In addition, I’d like to share that just a week into my four-month journey, I feel as though my ongoing ear issues are gradually dominating my life. I am incredibly grateful for this travel opportunity, and while my health isn’t at risk in a serious way, these ear complications are becoming quite overwhelming. Could there be surgical options available? Might there be an underlying health concern that I’m unaware of? It doesn’t seem normal to be plagued by constant ringing, popping sounds, and wax buildup in my ears. Moreover, it feels excessive to have to apply products in my ears every time I shower.
Injury to the Sciatic Nerve
At 25 years old and weighing 135 pounds, I am currently taking naproxen and Lyrica to manage my sciatic nerve injury. The pain in my right leg has made it incredibly difficult for me to remain upright. It’s been two weeks since I first sought treatment; I consulted a physician who advised medication and attended a physiotherapy session. Initially, I experienced some relief after the appointment, but unfortunately, the pain returned the following day—even the prescribed home exercises exacerbated my discomfort. Just yesterday, I attempted the cobra pose, along with the flossing technique, which only heightened my pain. I find it nearly impossible to stand for more than a few seconds before the discomfort becomes intolerable. Additionally, I have an appointment with an osteopath on Tuesday, but I can't shake off my worries— is it normal to still struggle with walking after two weeks? Although I am experiencing some numbness in my toes, I haven’t encountered any loss of bladder or bowel control, worsening numbness, or weakness in my legs, so I feel stable in that regard. Nonetheless, I fear the possibility of never fully recovering and being left with a lasting disability. The pain is overwhelming, adding to my anxiety about the future.
