PolyCystic Ovarian Syndrome PCOS
September 04, 2018 9:58 am
PolyCystic Ovarian Syndrome PCOS is a complex condition. The exact cause of PCOS is unknown however, it involves hormones imbalance and multiple ovarian cysts, irregular menses, and infertility. In some cases, PCOS can be compounded by diabetes, hypertension and other metabolic conditions. PCOS has been shown to effect approximately 10% of women of childbearing age with symptoms of menstrual abnormalities, poly cystic ovaries, and excess androgen (male sex hormone). PCOS should be diagnosed by ensuring there are no other underlying endocrine issues. There are several associated disease processes that seem to be related to PCOS. These related disease processes are Type 2 Diabetes, higher depression and anxiety, increased cardiovascular risks, stroke, hyperlipidemia, sleep apnea, overall inflammation, and endometrial cancer.
Anatomically, numerous cysts are found on the ovaries. These are usually diagnosed by ultrasound, blood levels of hormones, and symptoms described above.

Bariatric Surgery can improve PCOS in those individuals with Type 2 Diabetes Mellitus. Further information on weight loss surgery and its effect on PCOS here.
Calcium Lab Results
June 05, 2018 3:26 pm
Calcium is measured to evaluate function and adequacy of a physiologic processes. Calcium plays a critical role in several body functions such as, coagulation pathways, bone health, nerve conduction, and other functions. It is important whenever you are evaluating laboratory results that you look at the whole picture of the person, including medications, other laboratory studies and health history. One value is not a stand alone result. There are many factors that effect calcium results.
Factors that effect calcium results: (not an all inclusive list)
The two most common issues following Weight loss Surgery or Duodenal Switch may be albumin level and Vitamin D level. Please see past blogs on Vitamin D. Magnesium may also play a role in a Duodenal Switch patient.
The most common calcium result drawn is the total calcium level. Laboratory results may not explicitly label it as such, however, it measures the calcium that is bound to protein. Ionized calcium is the free calcium that is representative of the true total calcium. Ionized Calcium can be measured by ordering specific lab. Alternatively, the Ionized calcium can be calculated by the following formula: Corrected calcium mg/dL = (0.8 * (Normal Albumin – Pt’s Albumin)) + Serum Ca ) or use the calculator at the bottom of this post.
The low Albumin level accounts for the low calcium level. This may be the reason for a patient with a low albumin/protein level, also having their calcium level reported as low. However, when adjusted for the protein deficiency the corrected calcium comes into normal range. Video of Trouseau’s sign of a patient with calcium deficiency.
The first step in a patient who has low calcium reported, is to make sure their protein and albumin levels are normal, along with Vitamin D.
Calcium levels are managed by two processes major regularly hormones and influencing hormones. Controlling or major regulatory hormones include PTH, calcitonin, and vitamin D. In the kidney, vitamin D and PTH stimulate the activity of the epithelial calcium channel and the calcium-binding protein (ie, calbindin) to increase calcium absorption. Influencing hormones include thyroid hormones, growth hormone, and adrenal and gonadal steroids.

There are a a number of skin conditions that are associated with the disease of obesity. Acanthosis Nigricans is characterized as areas of thickened, dark, velvety discoloration in body folds and creases. Usually seen in the armpits, neck, under the breasts, in the skin folds of the abdomen and groin. The exact cause of it at the molecular level is not clear other than seen frequently with insulin excess in the case of benign conditions. This symptom can give a warning about health conditions that require further investigation.
Patients may assume excessive sweating and poor hygiene are the causes of this condition- both of which are incorrect.
Acanthuses Nigerians is caused by acanthosis and papillomatosis of the epidermis (the outer most layer of the skin) pigmentation is usually not in this area, rather than pigment-producing cells. The skin proliferation abnormalities in acanthosis nigrcans are frequently associated with hyperinsulinemia and insulin resistance. This probably presents the best understanding of the pathology behind it. It suggests that the layer of skin gets thicker probably caused by some stimuli- as indicated above seen with insulin excess.
There are two forms of this condition: Benign and Malignant.
Benign forms are associated with obesity, insulin resistance, and type II diabetes.
Insulin resistance: Insulin is a hormone secreted by the pancreas that allows your body to process sugar. Resistance predisposes to type II diabetes.
Hormonal disorders: Hypothyroidism, Polycystic Ovarian Disease, and other endocrine disorders of adrenal glands are ovaries
Drugs: Certain drugs and supplements such as high-dose niacin, birth control pills, steroids, may cause acanthosis nigricans.
Malignant forms may be an indication of Gastro-intestinal cancer such as stomach, colon, or liver cancer.
Treatment: No specific treatment is available for acanthosis nigricans. Treating the underlying conditions may restore some of the normal color and texture to affected areas of skin.
