As if pregnancy wasn’t enough of a problem when it comes to women, weight gain and their thyroid, here’s yet another: Women have more thyroid problems than men simply because of breast tissue . Did you know that a woman’s breasts require almost as much iodine as the thyroid ?
So for women, iodine has to do double, or during pregnancy, even triple duty.
There’s even a condition named for this breast tissue iodine deficiency: Fibrocystic Breast Disease . Clinically, a woman with fibrocystic breast disease should be assumed to be thyroid deficient. It has also been reported that women with this specific iodine deficiency disease are also more likely to develop breast cancer than those that don’t.
Since men don’t have these problems, women are unfortunately the ones who are typically more prone to being iodine deficient.
Therapy for hypothyroidism is monitored at approximately six week intervals until stable. During these visits, a blood sample is checked for TSH to determine if the appropriate amount of thyroid replacement is being given. The goal is to maintain the TSH within normal limits. Depending on the lab used, the absolute values may vary, but in general, a normal TSH range is between to /ml. Once stable, the TSH can be checked yearly. Over-treating hypothyroidism with excessive thyroid medication is potentially harmful and can cause problems with heart palpitations and blood pressure control and can also contribute to osteoporosis . Every effort should be made to keep the TSH within the normal range.
Many sewage treatment plants use centrifugal pumps to transfer the nitrified mixed liquor from the aeration zone to the anoxic zone for denitrification. These pumps are often referred to as Internal Mixed Liquor Recycle (IMLR) pumps. IMLR may be 200% to 400% the flow rate of influent wastewater (Q.) This is in addition to Return Activated Sludge (RAS) from secondary clarifiers, which may be 100% of Q. (Therefore, the hydraulic capacity of the tanks in such a system should handle at least 400% of annual average design flow (AADF.) At times, the raw or primary effluent wastewater must be carbon-supplemented by the addition of methanol, acetate, or simple food waste (molasses, whey, plant starch) to improve the treatment efficiency. These carbon additions should be accounted for in the design of a treatment facility's organic loading.
