Concerns About Unexpected Weight Loss and Lab Results
A 29-year-old female, weighing 130 pounds (with a BMI of 18.1), presents with no significant past medical history and is not currently on any medication. She recently sought medical advice due to an unanticipated weight decrease of approximately 30 pounds over the past year. Following her consultation, several laboratory tests were performed, yielding normal results with a few exceptions: - White Blood Cell count (WBC) at 3.5 - Antinuclear Antibody (ANA) test showing a result of 1:320 in a homogenous pattern (with negative results for dsDNA) - Thyroid Peroxidase Antibodies (TPO AB) at 118.9 - Levels of Vitamin B12 and folic acid were found to be within normal ranges. What are your thoughts on this case?

It's understandable to be concerned about unexpected weight loss, especially when it amounts to 30 pounds over a year. In your case, the laboratory results show some noteworthy trends, particularly with the white blood cell count, the ANA test, and thyroid antibodies. Let's break this down to help you understand and address your situation.
Summary of Key Points:
- Unexpected Weight Loss: Losing 30 pounds is significant and should not be ignored, as it can be linked to various health issues.
- Lab Results:
- Low White Blood Cell Count: This could suggest a problem with your immune system, or it may be a benign finding that needs monitoring.
- Positive ANA Test: This indicates possible autoimmune activity, but further context is essential to interpret this correctly.
- Thyroid Antibodies: Elevated TPO antibodies may suggest a thyroid disorder, such as Hashimoto's thyroiditis, which can lead to weight loss and other symptoms.
Explanation:
The combination of these laboratory findings could suggest an underlying condition affecting your weight and overall health. Autoimmune diseases can lead to weight loss due to increased metabolism, systemic inflammation, or other health complications. It's essential to view these test results in the context of possible symptoms you may be experiencing, such as fatigue, changes in mood, or other physical changes.
Next Steps:
-
Monitor Symptoms: Keep track of any additional symptoms you may observe over the coming weeks. Note changes in energy levels, moods, appetite, and any other physical changes.
-
Focus on Nutrition: Since your weight is already on the lower side (BMI 18.1), prioritize a nutrient-dense diet. Consider small, frequent meals with high-calorie, nutritious foods like avocados, nuts, smoothies, and whole grains to support weight management.
-
Hydration and Rest: Staying hydrated and ensuring you get adequate sleep can help support your body as you navigate these health concerns.
-
Follow Up on Lab Results: Given the lab results, particularly the elevated TPO antibodies and low WBC count, you should consider following up for further evaluation. This could involve discussing these results with your healthcare provider to assess the need for additional tests or referrals to specialists, like an endocrinologist or a rheumatologist.
Final Note:
It's commendable that you're seeking information and are proactive about your health. Remember, understanding the reasons behind your weight loss is crucial, and there are many strategies to help regain your well-being. Maintaining close communication with a healthcare provider is vital to interpret your situation accurately.

Worried About a Bump on My Ear
For the past few years, I've observed a small bump forming on my tragus. I've never had that part of my ear pierced, so I didn't think much of it at first and wasn't particularly anxious about it. However, over the last three years, I've started to pay more attention to it, and its size has increased. The bump appears slightly red on the surface, but beneath it, it feels almost like a small stone. First and foremost, should I be worried about this situation? The bump is mostly painless, and I've been accustomed to it for some time now. Secondly, although this might sound like a questionable idea, would it be harmful to attempt to gently poke it with a sterile bobby pin at home? Thank you for your time and any guidance regarding the bump on my ear!
Concerns About Rectal Health Diagnosis in Elderly Patient
My mother, who is 77 years old, has been experiencing rectal bleeding which was initially attributed to hemorrhoids. Eventually, after considerable reluctance and fear, we persuaded her to undergo a colonoscopy. The findings from the procedure were concerning: At a 10 cm distance from the anal opening, an ulceration was identified that compromises almost two-thirds of the intestinal opening and extends about 3 to 4 cm downward. The lesion has a soft texture upon palpation. During the examination, seven biopsies were performed for further histopathological analysis. In the pathology report: Under microscopic examination, the samples exhibit tubular glands of varying shapes along with villous structures covered by tall columnar epithelium. The epithelium ranges from a single layer to multiple layers, known as stratified. The nuclei observed are larger than normal, elongated, and hyperchromatic, indicating a heightened level of activity, with an abnormal loss of their typical basal alignment. Instances of mitosis, or cell division, appear to be infrequent and orderly. Mucus production has decreased moderately. Additionally, the stromal tissue shows signs of moderate chronic inflammation. Blood tests and ultrasound results came back normal. The surgeon has recommended that another biopsy and pathology review be conducted. I would appreciate any insights or thoughts on this matter; my anxiety over the situation is overwhelming...
Dealing with Overheating: The Challenges I Face
Since hitting puberty, I've experienced exercise-induced migraines. This means that any slight increase in my body temperature or heart rate triggers a severe headache that lingers throughout the day, often leaving me with a flushed face that gradually fades. To manage this, I can only engage in pool workouts and must carefully monitor other physically demanding activities while relying on preventative medications. As someone who enjoys being active, this situation isn't particularly beneficial for my mental well-being or weight management. Recently, I've noticed a significant increase in my sensitivity to heat. For example, just yesterday, I needed to visit a neighbor urgently. I quickly donned some outerwear and drove over, only to arrive completely sweaty and bright red. The perspiration seems to gather around the back of my head and trickles down my neck, and if I don’t cool down quickly enough, I even begin to sweat behind my knees. While I acknowledge that my weight plays a role, this feels distinctly different. Additionally, I struggle to warm up when I feel cold, which could be related to iron levels. I’d appreciate any suggestions to bring up with my highly competent but perplexed doctor.
Should I Be Worried or Celebrate My Weight Loss?
At 29 years old and standing 5'11, I've unexpectedly shed 20 pounds since early December without making any deliberate efforts. When I visited the doctor in December, I tipped the scales at 185, and upon weighing myself this morning, I was surprised to find I now weigh 164. There might have been a few minor tweaks to my eating habits, but nothing significant. While I can't deny that I'm somewhat happy about this change, I also feel perplexed since I haven't actively pursued weight loss. Is there any reason for concern?
