Vomiting, Diarrhea, Fatigue, Weakness. Blood Work Shows Low MCH And High BUN. Foul Smelling Urine, Groin Pain. Concerned
You have chronic diarrhea, which could be due to multiple things. First, I noted you listed on your medical history, MTHFR (interesting, how you know that?). In any case, if you do have this gene defect, this could be associated with diarrhea-IBS, depression and chronic fatigue. The metallic smell of the urine and the abnormal MCH/MCHC could also be from MTHFR defect (causes abnormal vitamin B12 levels and you may get environmental poisoning). You should ask your PCP about treatment of this entity, as I suspect this is the cause of all your problems.
Also you listed you have hypothyroidism, so I suppose you are taking thyroid replacement therapy, so if your thyroid function has not been checked recently you may be taking too much medicine (levothyroxine) which can cause diarrhea. So make sure none of your meds is the culprit.
Other things to consider and ask your doctor are parasites, fat malabsorption, and celiac sprue.
The high BUN/Creatinine, is probably from dehydration, so keep yourself hydrated.
Hope I have answered your query. If you have any further questions, I will be happy to help.

Thanks for writing back.
You can get tested for poisoning (usually heavy metals) with a urine test. Other urine tests include a toxin screen, porphyrin level.
Heavy metals (such as mercury for example) are found in very very very tiny amounts in the environment including food, for example mercury is found in tuna. Usually your body can get rid of it and nothing happens. When you have this genetic defect (MTHFR) you are predisposed to heavy metal toxicity (your body cannot get rid of it). Things to avoid include: household chemicals, artificial scents, cleansers, pesticides, processed foods, etc.
Ask your primary care doctor to test you. Hope that answers your questions.
