unexplained weight loss blood tests normal - #18771
I am really freaked out because I’ve been experiencing unexplained weight loss, and my blood tests are normal. Like, I didn't even change my diet or exercise that much, but I noticed like 15 pounds just disappeared in about a month. At first, I thought maybe it was just stress from work or something but then I went to my doc, and they ran a bunch of blood tests and everything came back normal. No thyroid issues, no diabetes, nothing! I mean, it’s a relief that there’s nothing major but at the same time, I can’t shake the feeling that something's off. I feel kinda drained and even have moments where I’m really hungry but nothing feels satisfying. Has anyone else dealt with unexplained weight loss when blood tests are normal?? I heard that sometimes it might be related to digestion or even some hidden infections but my doctor has not really suggested much beyond what they tested for. I’m worried that I’m missing something important and that this weight loss could lead to bigger issues. What should I do next? Should I push for more tests or something? This whole situation is driving me kinda crazy!

Doctors' responses
Unexplained weight loss can definitely feel unsettling, especially when initial tests are normal. When blood tests don’t reveal an obvious cause, broadening the investigation makes sense to rule out less common possibilities. Though standard tests didn’t pick up anything, you might want to explore other potential causes with your doctor. Digestive issues could indeed be a factor, with conditions like celiac disease or inflammatory bowel disease occasionally presenting with weight loss before other symptoms become pronounced. Asking for a gastroenterology consult or additional digestive function testing might be worthwhile.
An evaluation for malabsorption or other gastrointestinal causes could shed light on absorption problems. Additionally, since you mentioned feeling drained, it might be worthwhile to screen for infections or autoimmune conditions, which can sometimes escape initial blood panels. Even chronic kidney or liver conditions, that subtly impact metabolism over time, should be reconsidered, potentially asking for specialized imaging or function studies.
Another consideration is hypermetabolism, where stress hormones or subtle metabolic changes elevate calorie usage, leading to weight loss. A detailed look at cortisol levels or a more thorough endocrine workup could highlight abnormalities not evident with basic tests. If you haven’t already, maintaining a comprehensive symptom journal, noting meals, physical symptoms, and stress levels, could provide your doctor with more context to identify or exclude issues. If your symptoms worsen or don’t provide resolution, you might want to advocate for a more extensive evaluation. Meanwhile, focus on ensuring adequate caloric intake and a balanced diet, perhaps with input from a nutritionist, to stabilize weight and ensure you’re meeting energy and nutrient needs during further investigative process.
