Elevated AST Levels in My Son
Subject: Male, aged 4.5 years, weight 16.5 kg, height 105 cm, typically healthy but experiencing elevated AST levels. In April, I took my son for a blood test due to his fatigue. The results indicated anemia with low iron levels, and his AST was slightly elevated at 40 (the normal upper limit is 35). At the time, he was recovering from a virus and had been coughing persistently for several weeks, which I attributed to the elevated enzyme. Fortunately, the other liver function tests and blood counts appeared normal (aside from the anticipated low iron). This week, I had him tested again and the AST level has risen to 44. Interestingly, he was very active just the day prior, participating in a soccer match and trampoline activities. While I have some concerns, my general practitioner doesn't seem overly alarmed. My son appears to be healthy overall, although he does have a minor issue with a slightly inward-turned femur that is being managed with physical therapy. I'm scheduled to see a pediatric specialist in a couple of weeks. Has anyone else dealt with similar AST level concerns in their children?

It seems you're understandably concerned about your son's elevated AST levels, especially given his previous health issues with virus recovery and anemia. Let's break this down:
Main Points
- Elevated AST levels can arise from various factors, including physical activity, viral infections, and other underlying health conditions.
- It's good that other liver function tests and blood counts are normal, which helps to narrow down potential concerns.
- Monitoring and discussing these results with a specialist is the right path, as you are already scheduled to do.
Explanation
AST, or aspartate aminotransferase, is an enzyme found in various tissues, including the liver and muscles. Elevated AST levels may indicate liver irritation or damage, but they can also be influenced by physical activity, muscle injury, or a recent illness. Since your son was active shortly before the most recent test, this might be a contributing factor to the elevated result.
Since he has been recovering from a virus and has involved physical activities, it's possible that these factors are affecting his AST levels. The slight increase can also be part of normal variations in enzyme levels, especially in young children.
Next Steps
-
Continue Active Monitoring: Keep an eye on your son’s energy levels, any new symptoms, or changes in behavior. Document these observations to share with the specialist.
-
Hydration and Nutrition: Ensure he is well-hydrated and eating a balanced diet rich in iron and other essential nutrients, which can support his overall health and recovery from anemia.
-
Limit Intense Activities if Concerned: While regular play is essential, if your intuition tells you he is not feeling well or if you're anxious about the elevated levels, consider moderating intense physical activity until you have the specialist's input.
-
Prepare for the Specialist Visit: Make a list of all questions and concerns you have for your upcoming appointment. Include details about his symptoms, any changes in his health, and the recent increase in AST.
-
Follow Specialist Recommendations: Based on the specialist's evaluation, be ready to follow any suggested tests, dietary modifications, or treatment plans.
It's completely natural to feel worried; you're doing the right thing by seeking answers and support for your son. Reach out if you have more questions or need further clarification!

Experiencing Unexplained Skin Sensitivity in Social Situations
At 17 years old and standing at 182 centimeters, I've been facing an unusual and troubling condition. My skin feels an intense stinging sensation all over whenever I'm in close proximity to my parents or other people. The discomfort is so overwhelming that it's almost impossible for me to remain seated. Interestingly, there’s no physical manifestation—my skin appears entirely normal without any signs of dryness, rashes, or itchiness. Yet, I endure this sharp, burning pain that seems to be beyond my control. This issue has been intensifying, leading me to isolate myself more, which, in turn, exacerbates my feelings of loneliness. I'm curious if anyone else has encountered a similar experience. Could this potentially relate to a nerve or nervous system issue? I would also like to know what type of healthcare professional or specialist I should consult for further evaluation.
Inability to Sneeze: Potential Neural Communication Issues
Hello. I’m seeking assistance to comprehend my situation and explore possible remedies. I’m a 25-year-old male working as a software engineer and currently not taking any medications. For the last two years, I have experienced an inability to sneeze. This issue first arose following two significant incidents involving exposure to neurotoxic substances, which led to a variety of neurological symptoms. 1) **Vitamin B6 Toxicity**: Over a span of 4-6 weeks, I received seven intramuscular injections of a B-complex vitamin, each containing 100mg of Vitamin B6 in the pyridoxine form. Shortly after beginning these injections, my health rapidly declined, and numerous symptoms emerged. Research has identified pyridoxine as potentially neurotoxic, with recent documentaries and studies — particularly from the Australian community — raising awareness about this condition. In response, Australia’s Therapeutic Goods Administration (TGA) has taken steps to restrict the sale of B6 supplements and to lower their permissible amounts. For more insight into the seriousness of this issue, you can find several informative short documentaries on the ABC News YouTube channel. 2) **Insecticide Exposure**: While undergoing the B6 treatment, I also encountered a concerning situation where I inhaled toxic insecticide fumes. Not realizing the danger due to nasal congestion from a minor illness, I sprayed a considerable amount of insecticide in my room. It was only after I started coughing that I realized I had been breathing in these harmful fumes. It occurred late at night when I was already feeling unwell, and I opted to go to sleep shortly afterward. Both incidents occurred in September to October of 2021, after which I began to experience an alarming array of around twenty symptoms affecting my sensory, motor, and autonomic nervous systems. I developed severe numbness and tingling in various parts of my body, involuntary muscle movements, ataxia, facial numbness accompanied by a loss of muscle volume in my face due to nerve damage, and symptoms that resembled diabetes such as excessive thirst and fatigue post-meals. Other issues included rapid heart rate, skin lesions, an inability to sweat, extreme muscle weakness, and significant psychological symptoms, including emotional numbness and anhedonia. Virtually every area involving nerves seemed to be impacted. Now, 18 months later, I’ve made considerable progress, with most of the symptoms easing, but I still struggle with the inability to sneeze. Recently, after experiencing a flu, I noticed that my body failed to sneeze about 90% of the time. I feel the urge to sneeze starting deep in my lungs, traveling to the tip of my nose, yet it rarely culminates in an actual sneeze. Instead, I feel pressure released in alternative ways, sometimes sensed as pressure in my head, and occasionally, I experience tears running from my eyes and nose when the sneezing sensation arises, yet no sneeze follows. Despite waiting a year and a half for recovery and seeing improvements in my larger nerves, these specific bodily functions remain unresolved. A recent electromyography (EMG) and nerve conduction study (NCS) conducted two weeks ago returned normal results, which aligned with my awareness of the recovery in my larger nerves and muscles during this period. Through my research, I’ve discovered that the trigeminal and cranial nerves play a crucial role in initiating a sneeze, suggesting the presence of a signaling issue. I would greatly appreciate guidance on this matter.
Lower Lip Abscess in a Young Child
My four-year-old is dealing with a lower lip abscess. What began as a small crater on his lip last Sunday rapidly progressed to a pus-filled lesion by Monday night. By Wednesday evening, we managed to see a pediatrician who admitted him for intravenous antibiotic therapy. Since being hospitalized on Wednesday night, he has been receiving Sulvacil through an IV. A general surgeon evaluated him yesterday but chose not to perform an incision for drainage, stating that managing a lip wound would be quite challenging at his age. Currently, I'm feeling uncertain about the progress of his condition, as the abscess appears to still contain pus. It seems to swell and then reduce in size only to fill up again. Despite this, my child remains lively and has a good appetite, though he does experience discomfort when trying to chew. I’m left wondering if we are observing any tangible improvement, or if it might still be too soon to judge the situation?
Persistent Vomiting and Confounding Endoscopy Findings
I'm struggling to articulate my situation adequately, but I'll share everything and hope not to overlook any details. I'm 16 years old, standing at 5 feet 7 inches tall, and weighing 140 pounds. My blood tests have returned normal results, although I do have slightly low vitamin D levels, and my stool samples have come back clear. My current medication regimen includes 30 mg of Vyvanse, 20 mg of propranolol taken twice daily, 300 mg of gabapentin at night and 150 mg in the morning, and I recently began taking 25 mg of amitriptyline a week ago. Since I was about four or five, I’ve experienced unusual digestive issues, such as diarrhea, stomach cramps, constipation, and acid reflux, with the most alarming symptom being unexplained vomiting. Daily abdominal cramps and constipation are common for me, and surprisingly, these symptoms don’t seem to be influenced by my diet or activities. Around the age of five, I started to vomit inexplicably, particularly during times of excitement like the Super Bowl, birthday celebrations, or, most notably, vacations. When I turned 12, my condition worsened significantly after contracting COVID-19. I started experiencing dry heaves or vomiting almost every morning, which led to frequent school absences, severe migraines concentrated mostly on the left side of my forehead, and worsening stomach troubles. Living in Washington, I consulted numerous specialists at Swedish, including both an allergist and a gastroenterologist. The allergist suspected mast cell disease and prescribed Cromolyn, which unfortunately did not provide any relief. The gastroenterologist suggested that I had an issue related to my "lizard brain" and advised me to “find a hobby.” I also visited a cardiologist due to low blood pressure, where I was diagnosed with neurocardiogenic syncope. Recently, I convinced my general practitioner to refer me to a children’s hospital, where I underwent an endoscopy. To my surprise, the procedure revealed food remnants in my stomach despite having fasted for over 11 hours beforehand. Both the anesthesiologist and gastroenterologist expressed some skepticism regarding my fasting claim. I'm reaching out in search of any recommendations or insights. This ongoing illness has reached a point of frustration for me, and I desperately want to uncover its cause. The gastroenterologist who performed the endoscopy mentioned a possible gut-brain disorder, but this diagnosis is still quite vague. I am preparing for my next consultation and would appreciate any feedback. We have suspect cyclic vomiting syndrome for a while, but now I’m starting to wonder about gastroparesis as well. Honestly, I feel like this situation may have turned me into somewhat of a hypochondriac.
Understanding a Nodular Finding on My Appendix: Seeking Clarity
I'm a 22-year-old female, standing 4'9", with a background of EDS and anxiety. Recently, on January 30, 2026, I visited the emergency department due to kidney discomfort, which turned out to be a kidney stone. While reviewing my CT scan report to recall the size and location of the stone—still lodged and proving quite troublesome—I stumbled upon a mention of a nodular area on my appendix. This detail was not brought up by my doctor during my visit. Although I suspect it may not signal a serious issue, I'm curious if this is something I should discuss further with my primary care physician. Can anyone clarify what a nodular finding on the appendix means? I came across some information suggesting it could indicate a tumor, but I’m aware that online medical searches can often lead to misunderstandings. Any insights would be appreciated!
