I don't think anyone can tell you that, for sure... Everyone is different and we each have our tolerances.
I'm not sure what you mean by not having markers for hypothyroidism or Type II Diabetes. The most common cause of hypothyroidism is Hashimoto's, which is an autoimmune condition that erroneously identifies the thyroid as foreign. Studies show that Hashimoto's can be caused by any number of things, ranging from genetics to an infection, such the Epstein Barr Virus that causes mononucleosis to environmental factors, such as exposure to pesticides/PCB's and other chemicals. It's possible the gas was instrumental in your diagnosis (though I'd say it might not have happened that quickly) and it's just as possible that something previous such as a childhood infection was the cause and it coincidentally showed up when it did or maybe something else was the actual cause and the gas was the trigger. That's impossible to say.
Although Type II Diabetes can be hereditary, it can also be a lifestyle condition and either way is largely preventable.
It's possible that the gas leak contributed to your daughter's allergies. An irritant that's present over a long period is likely to cause allergic reaction, as in the case of those exposed to something like cigarette smoke, pollen or other irritants. Once the irritant is removed the allergic reaction stops.
For the sake of discussion, IMO, if one were going to try to sue someone, it might be difficult to impossible to prove that a single factor was to blame for the hypothyroidism when there are so many possible causes. Since Type II Diabetes is, often, preventable, I'm not sure cause could be proven there either.
Please keep in mind that I'm not a doctor or an attorney... It's very unfortunate that this happened and I'm sorry your family has had to go through these problems.
LOL - well it would be kind of hard to sue yourself, wouldn't it?
Type I diabetes is autoimmune; Type II is not, though it's sometimes hereditary. Type II always stays Type II; it doesn't turn into Type I, though one can become insulin dependent with Type II if oral medications don't work for them. I have a sister with insulin dependent Type II Diabetes...
I've been doing quite a bit of research since you posted this thread and there are numerous articles regarding endocrine disrupters. There was a study done in Colorado, but I haven't had a chance to look at the whole thing yet. I'll take a look at it as soon as I can get the full text and try to post a link...
I am in a similar situation but with toxic mould exposure. I have CIRS (chronic inflammatory response syndrome). Chronic exposure to toxic substances = chronic inflammation. I have had cellular hypothyroidism for decades due to inflammation (not only toxic mould but insulin resistance - both increases inflammatory cytokines).
"Certain cytokines and other markers of inflammation may be associated with development of both type 1 and type 2 diabetes (Goldberg 2009)."
I fast and eat low calorie (poor appetite) which explains why I've never developed diabetes. And after decades of insulin resistance I should of been diabetic by now.
Just to add..an article on inflammation from PTT Health - Diseases Caused by Chronic Inflammation...
"Some diseases caused by Chronic inflammation happen fairly soon. Many take a long time, often ten to twenty years or more. Reducing inflammation can delay or even prevent many chronic diseases! Most of these diseases are far more preventable than curable – so it makes a lot of sense to make some effort to reduce chronic inflammation.
Here are some diseases with strong evidence currently being researched.
Alzheimer’s Dermatitis
Multiple Sclerosis
Arthritis
Diabetes
Myalgias
Arthritis, Rheumatoid Eczema
Nephritis
Asthma
Allergies
Fibromyalgia Osteoarthritis
Atherosclerosis Inflammatory Bowel disease Parkinson’s
Autoimmune disease Interstitial Cystitis Psoriasis
Cardiovascular disease Irritable Bowel Syndrome Sarcoidosis
Colitis
Joint pain
Sjögren’s Syndrome
Crohn’s
Lupus Erythematous Ulcerative Colitis"
Sorry to read, you/family lived with discomfot due to leaking gas. Wonderful, you daughter healed/recovering. Body is very complex. Nothing surprises me in the medical world, by what we ingest or inhale. Very possible, your body was fighting inhaled gas, which caused your thyroid to malfunction. Another member developed swollen thyroid/issues, after attracting a virus. My thyroid began to swell, after I began taking Klonopin.
Thyroid and diabetes go hand in hand. Most whom develop thyroid disease, also develop diabetes.
Wish you/family well.
