Understanding the Lack of Reaction to Insect Bites
As a 30-year-old male, I've observed a notable change in my body's response to insect bites over the last few years. This realization first struck me during a jungle hiking trip a few years back. I was under the impression that I had evaded mosquito bites entirely. However, I could clearly see them landing on me multiple times. To my surprise, the bite sites showed no signs of swelling, itching, or any discomfort at all. I vividly recall how much I despised insect bites during my childhood and teenage years. Yet, it’s been difficult to pinpoint the last time I experienced a typical reaction to a bite, although it likely ceased during my mid-20s. While this change is certainly a gift in many respects, it also poses some practical issues. Not long ago, while traveling, it became apparent that our accommodation was infested with bedbugs. If it hadn’t been for my friend mentioning their bites, I might have remained oblivious to the infestation and unwittingly carried them home with me. I can confirm that my immune system is not compromised in any way (as far as I know), and I have regular tests for HIV. Is there a reason my body no longer reacts to insect bites in the same manner as most people?

It sounds like you've experienced a significant change in how your body reacts to insect bites, and it’s great that you’re seeking clarity on this issue. The lack of typical reactions—like swelling or itching—could be linked to several factors, including changes in your immune response over time, which can sometimes occur as we age or due to environmental exposures.
Explanation
-
Immune Response Variability: As people age, the immune system can change, leading to less pronounced allergic or inflammatory responses to certain stimuli, including insect bites. It's possible that your body has adapted or become desensitized to insect saliva, which is what typically causes reactions.
-
Genetic Factors: Genetic predispositions can also play a role in how your body responds to allergens. Some individuals are naturally more tolerant to insect bites than others.
-
Environmental Factors: Frequent exposure to certain insects or environments may have contributed to your current state, leading to a type of acquired tolerance.
Despite the positives of reduced reactions, it’s understandable that it could lead to practical issues, like the situation you encountered with bedbugs. Recognizing bites can be essential for managing pests and avoiding them in the future.
Next Steps
-
Monitoring for Changes: Since this change has been ongoing, continue to monitor any new reactions to insect bites. If you begin to notice any unusual symptoms, keep a record of your experiences.
-
Protective Measures Against Bugs: To avoid issues like potential infestations, consider using insect repellent when outdoors and inspecting accommodations for pests when traveling.
-
Self-Education: Learn about the types of insects that are common in your area or places you travel to, along with their bites or stings. Being aware of what to look for can help you identify infestations or bites earlier.
-
Consulting with a Professional (if concerned): If you're uncomfortable with this lack of response and it impacts your daily life, consider seeing an allergist or immunologist for a more tailored evaluation and understanding.
Your situation does have its benefits, but staying informed and prepared can help manage any practical implications. If you have any further questions or need additional advice, feel free to ask.

Understanding High AST/SGOT Levels in Blood Test Results
As a 16-year-old male with a height of 174 cm, I recently underwent a blood test in the morning. Upon reviewing the results, I discovered that my AST (aspartate aminotransferase) level was significantly elevated at 125.8, prompting me to seek insights into the possible reasons. I have been taking minimal doses of paracetamol lately due to a flu, and I just started going to the gym this week. These factors are the only explanations I can think of for the increase in my AST levels. Should I be worried about these findings? Additionally, my ALT (alanine aminotransferase) level registered at 52.7, which is also on the higher side. Similarly, my GGT (gamma-glutamyl transferase) was recorded at 58.9, again slightly elevated. My iron levels indicated 32, which is also considered high. Fortunately, all my other test results were within the normal range.
Inquiry About Biopsy and Insurance Billing Practices
I’m a 36-year-old male without any notable health concerns in my past. Recently, I underwent a comprehensive dermatological examination to assess the condition of my moles. During the assessment, the dermatologist evaluated all the spots and chose to perform a biopsy on the last one he examined, expressing that it appeared slightly unusual compared to the others. While I’m not a skin specialist, I personally noted several other moles on my body that appeared more peculiar than the one he selected. He assured me that he didn’t anticipate any serious issues arising from it. I’m curious to know whether it’s a common practice for doctors to conduct a biopsy primarily for the purpose of insurance billing. I’m not particularly upset if that is the case; it’s understandable that medical professionals need to generate income for their services.
Can You Overuse Eye Drops?
Hello! I'm a 25-year-old female, standing 5 feet 9 inches tall and weighing 230 pounds. Currently, I'm dealing with styes in both of my eyes and have been instructed to use Polymyxin B Sulfate drops for treatment. My physician recommended administering one drop into each eye every six hours, which amounts to four doses in a day. Unfortunately, I've been struggling to sleep well because of the significant discomfort in my eyes. In my distress, I inadvertently took the drops too close together without keeping track of the times, and only realized my mistake after my boyfriend pointed it out. According to him, I dosed myself at midnight, then again at 5:30 AM, followed by 9:15 AM, and once more at 11 AM. I'm unsure how eye drops work compared to oral medications, especially regarding safety and dosage since they're applied directly in the eye. Should I consult with my doctor about when to take my next dose?
Concerns Regarding Brain-Eating Amoeba Infection After Pool Incident
Greetings. Earlier today, while tending to a family friend’s yard, I inadvertently stepped onto the protective cover of their pool, which, as you might imagine, tore away and led to my unexpected plunge into the water. This pool had been out of use for approximately nine to ten months. Due to the sudden nature of my fall, some of that water unfortunately entered my nostrils. The water wasn’t cloudy or murky green; rather, it had a darker gray tint, reminiscent of river water. From my observations, it appeared there was no discernible algae present, although I cannot state that definitively. My location is Northern Italy, where I believe there has only been a single reported incident of this kind. Am I in danger of having encountered a brain-eating amoeba? I appreciate any insights you can offer.
Unidentified Insect Bite: Seeking Answers
Hello everyone, I'm an 18-year-old female, and roughly two weeks ago, I experienced a mysterious insect bite. To this day, I have no idea what it could have been. I've visited urgent care, the emergency room, and consulted my primary doctor, yet none have been able to identify the cause. I'm receiving care, and it's being managed to the best of their abilities. However, my primary concern is uncovering the nature of this bite. I do have some photos showing the progression of the symptoms. The initial itchiness caught me off guard while I was asleep; I didn’t see the insect responsible. When I woke up, I immediately cleaned my bedding but found no signs of any bugs. For about a week afterward, I endured severe pain in the affected area, which felt like it was being pierced repeatedly with a heated needle. Although I noticed some hardening beneath the skin, that has since diminished. About 3 to 4 days post-bite, the area began to feel numb, and it remains quite insensate. Any insights or advice would be greatly appreciated!
