Inappropriate weight gain has long been recognized as a characteristic of hypothyroidism (one cause of DTSF). This symptom of DTSF can present in the same fashion as other DTSF symptoms caused by Wilson’s Temperature Syndrome. It can appear or worsen after a major stress, be related to one or many of the other symptoms of Wilson’s Temperature Syndrome; and be well correlated with a consistently low body temperature pattern. A patient’s weight can depend on their diet, exercise, female hormones, adrenal hormones, and thyroid hormones as well as body shape and stress levels. Of course, not all of these factors can be controlled with thyroid hormone medication. However, it has long since been made clear that decreased thyroid system function can greatly affect a patient’s ability to maintain normal weight. If a person’s DTSF is overlooked when approaching their weight problem, the approaches taken may not fully address the underlying problems. Such approaches, therefore, often result in the gaining back of the patient’s weight after the approaches have been discontinued. Since Wilson’s Temperature Syndrome is essentially a starvation coping mechanism gone amuck, severe dieting can actually make the problem worse causing the patient to gain all the weight back and then some. If people are having a problem maintaining their weight, it would be worth taking a careful history to see if the patient’s weight problems came on after a major stress together with other symptoms of Wilson’s Temperature Syndrome and a low body temperature pattern (WS?).
