why am i losing weight so fast - #20807
I am really worried about something that's happening to me lately. I started noticing I am losing weight so fast over the past month, and honestly, it’s freaking me out a bit. Like, I didn't change my diet much, maybe just been a lil more active since the weather got nicer, but not by a ton or anything. I mean... I just went to the doc last week, and she said my thyroid levels were normal, which I thought was good? But then at my last appointment, my weight was down by over 10 pounds. I keep asking myself, why am I losing weight so fast? One day, I felt tired and a little dizzy after working out, and then another day I was really hungry but I couldn't eat much before feeling full. Kinda weird, right? I did have some stomach aches too, but nothing major I thought. I'm trying to keep a positive attitude, but I can’t shake this feeling that something's off with my body. Do you think it could be stress, or maybe something else? Like, why am I losing weight so fast, and should I be more concerned or is this just normal? Thanks for any advice!

Doctors' responses
Unintentional fast weight loss can be concerning, and figuring out the cause is important. Since your thyroid levels are normal, we can likely rule out hyperthyroidism, which is good. However, there are several other reasons you might be experiencing this. Causes could range from stress, which affects metabolism and appetite, to more serious issues like unexplained gastrointestinal problems or malabsorption conditions. The tiredness and dizziness after working out, along with feeling full after eating small amounts, might suggest digestive issues affecting nutrient absorption. Stomach aches, though subtle, could also indicate an underlying stomach or intestinal problem. It’s worth considering if you’ve experienced changes in appetite, dietary intolerances, or symptoms like diarrhea or constipation, as these could indicate issues like celiac disease, Crohn’s disease, or other inflammatory conditions. Stress is another potential factor; chronic stress can lead to increased cortisol levels, altering metabolism and appetite. However, given that you’ve lost over 10 pounds within a month, visiting a doctor again might be wise to delve further into this, perhaps with more specific tests like blood panels, imaging, or dietary assessments. Keeping a food diary, noting details like meal times, portion sizes, and any symptoms afterward might provide data that helps in diagnosis too. Meanwhile, staying hydrated and ensuring that you’re eating balanced meals of adequate calories is important. If your symptoms like dizziness or unexplained fatigue persist or worsen, it’s crucial to seek medical attention promptly.
