Health Concerns After Starting Levothyroxine
I've been taking levothyroxine for my hypothyroidism for about a week now and I need to share my experience so far. On the very first day, I noticed a strange sensation in my abdomen, particularly around my navel, as if it was drawing inwards? I’ve been trying to alleviate that feeling by bloating my stomach, but it persists. By the second day, I was hit with diarrhea, going to the restroom four times in a single day. On day three, I faced a struggle as I was completely unable to have a bowel movement while still experiencing discomfort in my abdomen. Day four brought a slight improvement, but I didn’t manage to go until later that night, and even then, it was just a small amount. I visited my general practitioner on day five to discuss these ongoing symptoms. Upon examination, she noted that my abdomen was soft and not tender to touch, but I was unsure what that indication meant. She listened to my abdomen and suggested it might be gastroenteritis or possibly food poisoning. Day six was similar, with difficulty in having a bowel movement. I finally managed to have a normal stool, but there was also diarrhea, leaving me with a feeling of fullness and bloating. Now, on day seven, the strange sensation in my stomach continues. While I have been able to pass gas, I've got no blood in my stool, no fever, and the pain isn't severe. I can’t help but worry—am I at risk of septic issues, or could there be something more serious like a perforated bowel or appendicitis? What about the possibility of bowel or stomach cancer?

It sounds like you're experiencing a range of gastrointestinal issues since starting levothyroxine, including abdominal sensations, diarrhea, and difficulty with bowel movements. These symptoms can understandably cause worry, especially when considering potential serious conditions. However, it's important to remember that changes in bowel habits and sensation can often be attributed to factors such as medication adjustments, dietary changes, or mild infections.
Explanation
Levothyroxine is a medication used to treat hypothyroidism, and while it generally doesn't cause abdominal symptoms, starting a new medication can sometimes disrupt your gastrointestinal system. Your doctor's examination indicated that your abdomen is soft and not tender, which is a reassuring sign that there is no immediate distress. The symptoms you describe, such as diarrhea and then difficulty with bowel movements, can commonly occur due to changes in diet, stress, or a temporary upset in your digestive system, such as mild gastroenteritis.
Next Steps
-
Hydration: Prioritize staying hydrated, especially since you've experienced diarrhea. Drink plenty of water, and consider oral rehydration solutions to replenish lost fluids and electrolytes.
-
Diet Adjustments: Focus on a bland diet to help calm your digestive system. Foods like bananas, rice, applesauce, and toast (often referred to as the BRAT diet) can help. Avoid spicy, fatty, or heavy foods for now.
-
Monitor Symptoms: Keep a daily record of your symptoms, noting changes in your bowel habits, any new symptoms that arise, and your overall feelings of well-being. This can help identify patterns or triggers.
-
Gentle Activities: If comfortable, try gentle activities like walking, which can help with digestion and relieve bloating and discomfort.
-
Follow-Up Care: Since you’ve already seen your doctor, continue to keep them updated about your ongoing symptoms. If there are any significant changes, such as persistent pain, vomiting, or worsening diarrhea, don’t hesitate to reach out.
It’s good to express concerns, but the signs you've described, including the absence of severe pain or blood in the stool, are typically not indicative of serious conditions like appendicitis or cancer. However, if your symptoms continue or change significantly, or if you develop new symptoms, ensure that you seek further medical advice promptly. You're taking positive steps by monitoring your health, and together with your healthcare provider, you can address these concerns effectively.

Interpreting My Recent Test Results in Light of My Symptoms
I visited my physician today and received some concerning lab test results. I’m a 21-year-old woman, weighing 180 pounds and standing at 5 feet 3 inches tall. The tests revealed elevated levels of C-reactive protein at 9.6 mg/L, an erythrocyte sedimentation rate of 29 mm/hr, MCG at 26.1 pg, and an RDW-CV of 15.3%. Although my hemoglobin and hematocrit values fall within a healthy range, my ferritin levels are still pending. For most of my life, I have struggled with gastrointestinal issues, though there has been a recent shift from constipation to frequent, soft bowel movements multiple times daily. Additionally, I am experiencing abdominal discomfort in the lower central area and also higher up, under my ribs. Each morning, I wake up feeling nauseated. During my examination, the doctor discovered a significant anal fissure externally, which aligns with the bleeding I've been having, but they didn’t conduct a deeper investigation. I’m worried that these symptoms might indicate Crohn's disease, and I would greatly appreciate any insights that could help clarify my situation. Thank you for your assistance.
M30 (Thirties) - Awaiting Guidance on MRI Results
I just received my MRI results and now I face a waiting period of two weeks before discussing them with my physician. I would appreciate your insights into their significance and the possible treatments that could be recommended, if necessary. To summarize my situation, I was involved in a car accident around two months ago, which resulted in a mild neck sprain, often described as whiplash. From my understanding of the results, it seems that any noted issues are likely attributed to normal wear and tear that occurs naturally as we age. Nevertheless, if there are indications within the report that might link back to the car accident, this information would greatly benefit my situation. Additionally, I would like to know your opinion on what treatment options may be advisable at this stage, if any are deemed necessary. Thank you for your assistance!
Abdominal Discomfort
I'm a 20-year-old female, and recently I suspect that a meal I consumed has led to some stomach discomfort. It's quite unusual for me to experience such pain after eating, so this was a bit puzzling. Unfortunately, the discomfort escalated into severe cramps, and I felt an urgent need to visit the restroom, yet nothing happened. The following day, I found myself unable to eat much; any food intake would trigger more pain, although overall, I felt fine otherwise. Currently, I'm waking up during the night needing to go to the bathroom, but again, there's no result. I've also noticed that my bowel movements have not been particularly regular leading up to this point. Is it possible that this is simply a case of having consumed something problematic while also dealing with constipation, or could there be another underlying issue?
Seeking Guidance After X-ray Reveals Significant Colon Backup
On Monday, I found myself in the emergency room after experiencing several days of persistent vomiting. I thought it was related to my resumption of Ozempic (0.25 mg), which I had halted back in May and then restarted on my own after two weeks. I understand now that I shouldn’t have made that decision without discussing it with my doctor. Regardless, I was battling nausea and had not been able to keep any food down, raising concerns about my condition. (For context, I originally began taking Ozempic in April 2023 to manage my type 2 diabetes.) The doctor ordered an X-ray of my abdomen. While my stomach appeared normal, the results revealed that both of my colons are completely obstructed. I was unaware that my situation had deteriorated to this extent. For over a year, I've only managed to have a bowel movement once a week but didn't realize I was harboring such a significant buildup. Following the X-ray, my doctor recommended a regimen of 34 grams of MiraLAX over three days and suggested adding senna to my Ozempic treatment to aid in stool regulation. A bit about my health: I'm a 33-year-old female, taking metformin, atorvastatin, several antidepressants, as well as minoxidil and spironolactone for my androgenic alopecia. Unfortunately, I lead a sedentary lifestyle and have some extra weight to contend with. My height is 4 feet 9 inches, and I weigh 137 pounds. Staying properly hydrated is a challenge for me, as I seldom feel thirsty; on most days, I’m lucky to drink two bottles of water. Next week, I have an appointment scheduled with my primary care physician, where I plan to share this new information with her. I last saw her six months ago. I’m growing increasingly anxious about my situation. If daily use of stool softeners or laxatives fails to resolve this blockage, what might the consequences be? Could surgery be a potential necessity? The wait until my next appointment feels unbearable, and I’m eager for guidance and clarity on the path forward. I've attempted to provide thorough details regarding my situation, so please feel free to ask any follow-up questions. Thank you for taking the time to read my post!
Presence of Air in Stomach Identified on Chest X-Ray
A 46-year-old woman presents with a medical history that includes Hashimoto’s thyroiditis, POTS syndrome, gastritis, asthma, and interstitial cystitis, along with various allergies. She is currently taking Unithroid, desmopressin, ferrous sulfate, and famotidine. Recently, she underwent a chest X-ray to investigate asthma-related symptoms, particularly breathlessness. As a result of the examination, she received a prescription for an inhaler, additional allergy medications, and steroids. Fortunately, the X-ray revealed that her lung condition was clear, which was a relief. However, the physician noted a significant amount of air present in her stomach. The doctor plans to consult with the radiologist to gain further insights into this finding. The patient is now curious about potential causes for the air accumulation and its level of concern, especially considering her existing conditions of gastritis and a hernia, which the doctor assured her were not serious issues.
