why am i losing weight so fast

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.
