I have been seeing Dr. Segu for years. Even though his practice is expanding, I still receive the personal care and attention that I want from my Endocrinologist. He's very patient with me and answers my questions in ways that I understand. I feel very informed about my care, which I really appreciate. His staff is delightful, and I always receive top notch service from them whether it's over the phone or in person. I applaud Capital Endocrine & Diabetes for going the extra mile to offer complete care, from sleep studies to nutrition, eye screening and (most recently) blood draws! I have and will continue to refer friends.

Dr. Segu has been a wonderful doctor. He listens and is thorough in his evaluation. There's a lab on-site (excellent service there too) so getting tests is easy and it was not busy. Dr. Segu goes over my labs personally. I feel he genuinely cares about his patients. He's trustworthy and I value his opinion. The staff is pleasant and I didn't have to wait long to be seen! I'm very pleased with the practice.

Diabetes Mellitus

According to the Centers of Disease Control more than 29 million US adults have diabetes, and 25% of them don’t know it. About 86 million US adults— more than a third—have prediabetes, and and 90% of them don’t know it *. The prevalence of diabetes has increased tremendously over the years and if current trends were to continue it is estimated that 1 in 3 US adults would have diabetes by 2050.

What is Diabetes?

Diabetes is a chronic health condition and has been associated with variety of long-term complications including damage to the eyes (retinopathy), kidneys (nephropathy), nerves (neuropathy) besides higher incidence of heart disease, strokes and disease of the peripheral vascular system. One of the major goals of treatment for this condition is to reduce the risk of these complications. There are two major types of diabetes.

Type 1 Diabetes

Type 1 diabetes accounts for ~5% of all cases of diabetes. This condition results from the destruction of insulin-producing beta cells in the pancreas by the patient's immune system. Insulin is the main treatment for type 1 diabetes, and this can be accomplished by injections, inhaled insulin or an insulin pump. Fortunately, insulin treatment is more flexible and user-friendly than ever before due to advancements in medical science and technology.

Type 2 Diabetes

Type 2 diabetes accounts for ~90-95% of all cases of diabetes. This condition results from a combination of insulin resistance, relative insulin deficiency, and additional defects in metabolic pathways. Type 2 diabetes is closely associated with other metabolic disorders such as obesity, abnormal lipids and high blood pressure. Sedentary lifestyle and unhealthy eating habits also contribute to this type of diabetes. It can be diagnosed fairly easily via standardized blood glucose testing. Early on, this condition typically responds to a combination of diet, exercise and pills. As the condition progresses, patients usually require injectables including insulin. Several new medication classes are now available to manage this condition.

Thyroid Disorders

An estimated 15 million people in this country are suffering from some type of thyroid disorder that has yet to be properly diagnosed. An additional 15 million have been diagnosed and treated.

Thyroid Nodules

Thyroid nodules are a common clinical finding, with an estimated prevalence on the basis of palpation that ranges from 3% to 7%. The prevalence of clinically inapparent thyroid nodules is estimated with US at 20% to 76% in the general population, with prevalence similar to that reported from autopsy data. Moreover, 20% to 48% of patients with one palpable thyroid nodule are found to have additional nodules on ultrasound investigation *. One of the important services that an endocrinologist could offer is a needle biopsy of these nodules to help distinguish between benign nodules from cancerous ones. Benign nodules are often followed over time unless they cause local pressure symptoms or lead to hyperthyroidism. Cancerous nodules are referred to a thyroid surgeon for surgical removal.

Other Thyroid Disorders

Some of other thyroid disorders which are common in the population include disorders of thyroid function- hyperthyroidism (overactive thyroid), hypothyroidism (underactive thyroid) and thyroiditis (thyroid inflammation) and disorders of thyroid structure- goiter (thyroid enlargement). Many of these are occur at a higher frequency in women than in men. An endocrinologist/thyroid specialist can evaluate for signs and symptoms of these disorders and order appropriate blood tests and scans to diagnose these conditions. Following this, a patient-specific treatment plan can be developed by the endocrinologist.

Continuous Glucose Monitoring

Overview

One of the main goals of treating a patient with diabetes is to control blood sugar levels. It would be ideal to return patients’ 24- hour blood sugar profile towards normal healthy pattern seen in non-diabetic subjects. Technological advances have allowed physicians and patients to view these patterns continuously using Continuous Glucose Sensors. Broadly there are two applications of continuous glucose sensors. Sensors for professional use are used on patients by endocrinologists/diabetologists as a test to analyze glucose patterns and plan appropriate treatment modifications. On the other hand, continuous glucose sensors are available for ongoing patient use to enable patients to follow their glucose patterns in real-time. Alarms and notifications are made possible so patients can take appropriate corrective measures in anticipation.

Osteoporosis

Overview

The word “Osteoporosis” literally means “porous bones”. It is a metabolic disorder of bones resulting in progressive weakening and increased likelihood of breaking bones (fractures). It is estimated that about 54 million Americans have this condition. Up to one in two women and one in four men 50 years or older will break a bone in their lifetimes due to osteoporosis. Fractures from osteoporosis most often occur in the hip, spine (vertebral column) or wrists but other bones may break too. Pain, disability, immobility, loss of height are some of the known sequelae of fractures. Sadly, one in five senior citizens who break a hip die within a year (from complications related to fracture or from surgery done to repair the fracture).

Diagnosis

Bone mineral density test is widely used to evaluate for bone quality. It is used as a screening tool as well as a test to monitor for serial changes with treatment interventions. An endocrinologist can evaluate for potential secondary causes of osteoporosis and offer specific medications to help reduce risk of future fractures and improve bone density.

Obesity

Prevalance

The prevalence of obesity is increasing at an alarming pace across the world. The World Health Organization (WHO) predicts that by the year 2015 there will be 2.3 million adults worldwide who will be overweight and more than 700 million will be obese. In the US, obesity has doubled in its prevalence in adults aged 20-74 between 1980 and 2010. Presently about 35% of US adults are estimated to be obese and another third overweight.

Obesity as Chronic Disease

For a long time obesity was not considered by medical community as a significant medical condition. It is now considered as a disease by NIH (National Institutes of Health), WHO, FDA (Food and Drug Administration), AMA (American Medical Association), The Obesity Society (TOS), American Association of Clinical Endocrinology (AACE), Endocrine Society, American College of Cardiology and several other medical societies and associations.

Associated Health Problems

Obesity has been associated with over 25 medical conditions. In other words obesity increases risk of developing other health problems such as type 2 diabetes, hypertension (high blood pressure), dyslipidemia (abnormal cholesterol panel), heart disease, degenerative arthritis (osteoarthritis), sleep apnea, gall bladder disease, acid reflux, infertility, fatty liver, breast cancer, colon cancer, prostate cancer, polycystic ovary syndrome etc.

Excess body weight may sometimes be due to another medical condition such as Cushing’s syndrome, hypothyroidism (underactive thyroid), lipodystrophies etc.

Benefits of Weight Loss

Even modest weight loss of 3-5% in these individuals has been shown to provide various metabolic benefits including lowering of blood sugars, blood pressure and improvement in cholesterol panel. Other potential benefits include improvements in sleep apnea, sexual function, mobility, mood etc.

The American Heart Association, American College of Cardiology, and The Obesity Society all recommend that lifestyle modifications (dietary changes and increasing physical activity) as the backbone of treatment for obesity *. For those needing additional help, today there are medication options and surgical options that are FDA approved.
