Proving that a substance does not cause or is not related to increased cancer risk is difficult. For example, antiperspirants are considered to possibly be related to breast cancer by some investigators and not by others. The official stance by the NCI is "additional research is needed to investigate this relationship and other factors that may be involved." This unsatisfying conclusion is presented because the data collected so far is contradictory. Other claims that are similar require intense and expensive research that may never be done. Reasonable advice might be to avoid large amounts of any compounds even remotely linked to cancer, although it may be difficult to do in complex, technologically advanced modern societies.


"Brittle" diabetes, also known as unstable diabetes or labile diabetes, is a term that was traditionally used to describe the dramatic and recurrent swings in glucose levels, often occurring for no apparent reason in insulin-dependent diabetes. This term, however, has no biologic basis and should not be used.[38] Still, type 1 diabetes can be accompanied by irregular and unpredictable high blood sugar levels, frequently with ketosis, and sometimes with serious low blood sugar levels. Other complications include an impaired counterregulatory response to low blood sugar, infection, gastroparesis (which leads to erratic absorption of dietary carbohydrates), and endocrinopathies (e.g., Addison's disease).[38] These phenomena are believed to occur no more frequently than in 1% to 2% of persons with type 1 diabetes.[39]
Weight loss surgery in those with obesity and type two diabetes is often an effective measure.[14] Many are able to maintain normal blood sugar levels with little or no medications following surgery[95] and long-term mortality is decreased.[96] There is, however, a short-term mortality risk of less than 1% from the surgery.[97] The body mass index cutoffs for when surgery is appropriate are not yet clear.[96] It is recommended that this option be considered in those who are unable to get both their weight and blood sugar under control.[98]
CBD, short for cannabidiol, is the main non-psychoactive compound found in marijuana and hemp. It does not interact with the body the same way as THC and cannot get you high. At the same time, CBD has many of the plant’s most significant medical and medicinal benefits. CBD can reduce seizures in epilepsy patients and a growing body of research finds it useful for reducing pain, acne, anxiety, inflammation and more.
