Hi, I am a looking for a diagnosis of what I may be suffering from. To clarify, for the last five years or so, I have been suffering from the following symptoms: chronic fatigue (this is by far the worst and most debilitating symptom), low mood (as a result of the chronic fatigue), itchy scalp, acne, dry skin, abdominal discomfort/flatulence, nasal congestion and an inability to gain weight. I have visited my doctor and I have had a whole host of medical tests performed, ranging from various blood tests, urine analysis, stool analysis and an upper gastrointestinal endoscopy, none of which have revealed anything unusual, and as a result, I have been diagnosed with Chronic Fatigue Syndrome, but I do not think that I have this condition, I believe that there is an alternative underlying medical cause for my symptoms, as CFS does not typically manifest itself with such an eclectic array of symptoms - any suggestions as to what it could be? (By the way, I have tried many different vitamin/mineral supplements, none of which have helped me).
You probably don't have CFS. Your doctor may have diagnosed you using the CDC definition, which is quite bad and very vague. The Canadian Consensus Criteria and International Consensus Criteria both heavily emphasize the symptom of Post-exertional malaise or post-exertional neuroimmune exhaustion. This means that a day or two after exercising you would feel extremely ill - as if you had a bad case of the flu and/or got run over by a truck.
If I had to pick something else for you to look into, it would be food allergies/intolerances. These can cause the GI problems and the skin problems, and could result in lack of weight gain and fatigue as well. You could try a food elimination diet to find intolerances, since lab results aren't really useful in that area.
As a side note - the symptoms of CFS (or Myalgic Encephalomyelitis in the rest of the world) are extremely eclectic. Far more than your current symptoms!
Thank you for your reply, I have considered the possibility that my symptoms could be related to a food intolerance of some sort and I have done some research into this, but it's just a case of identifying what food(s) it could be; I have been tested for celiac disease, but the results came back negative and I also eliminated dairy from my diet for one month to see if that would help my symptoms, but it did not, so I am still not sure of the source.
A proper elimination diet requires cutting back to just a few very safe foods for a week or two (rice, meat, potatoes, multi-vitamine), then introducing potentially problematic food groups every 3-5 days, like corn, gluten (there can be non-celiac intolerances/allergies), wheat, egg whites, egg yolks, corn, soy, etc. Then if you still have problems, you can try avoiding harder stuff like salicylates to see if there's an improvement and/or if things get worse when you start eating it again.
