Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure typically does not cause symptoms. Long-term high blood pressure, however, is a major risk factor for coronary artery disease, stroke, heart failure, atrial fibrillation, peripheral vascular disease, vision loss, chronic kidney disease, and dementia.
Metabolic syndrome is a burgeoning global problem. Approximately one fourth of the adult European population is estimated to have metabolic syndrome, with a similar prevalence in Latin America.  It is also considered an emerging epidemic in developing East Asian countries, including China, Japan, and Korea. The prevalence of metabolic syndrome in East Asia may range from 8-13% in men and from 2-18% in women, depending on the population and definitions used. [29, 30, 31]
A 2015 review of several studies found that restoring blood vitamin D levels by using supplements (more than 1,000 IU per day) reduced blood pressure in hypertensive individuals when they had existing vitamin D deficiency. The results also demonstrated a correlation of chronically low vitamin D levels with a higher chance of becoming hypertensive. Supplementation with vitamin D over 18 months in normotensive individuals with vitamin D deficiency did not significantly affect blood pressure.
Not so anymore. Thanks to the rising obesity epidemic in young people, kids and teens are getting these conditions — and they're getting them earlier than ever before. Some estimates say that nearly 1 in 10 teens — and over a third of obese teens — have metabolic syndrome. And a study of 375 second- and third-graders found that 5% had metabolic syndrome and 45% had one or two risk factors for it. https://i.ytimg.com/vi/-wDavU9u0rQ/hqdefault.jpg?sqp
Approximately half of individuals with hypertension have OSA, and approximately half with OSA have hypertension. Ambulatory BP monitoring normally reveals a "dip" in BP of at least 10% during sleep. However, if a patient is a "nondipper," the chances that the patient has OSA is increased. Nondipping is thought to be caused by frequent apneic/hypopneic episodes that end with arousals associated with marked spikes in BP that last for several seconds. Apneic episodes are associated with striking increases in sympathetic nerve activity and enormous elevations of BP. Individuals with sleep apnea have increased cardiovascular mortality, in part likely related to the high incidence of hypertension. http://www.sandysidhumedia.com/wp-content/uploads/2013/12/SSM_Logo_White.png

Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.

The second hormone that becomes involved when you begin to lose weight is a hormone known as leptin. Leptin is a hormone that is released from the fat cells to signal to the brain about how much fat we have in storage. To our body this is kind of like the indicator on a car telling us how much fuel we have in the tank. Leptin is also a messenger that is involved with controlling your metabolic rate AND your appetite.
When you have type 2 diabetes, your cells don't get enough glucose, which may cause you to lose weight. Also, if you are urinating more frequently because of uncontrolled diabetes, you may lose more calories and water, resulting in weight loss, says Daniel Einhorn, MD, medical director of the Scripps Whittier Diabetes Institute and clinical professor of medicine at the University of California in San Diego. http://www.sandysidhumedia.com/wp-content/uploads/2012/12/angelaquote1.jpg
Cataracts and glaucoma are also more common among diabetics. It is also important to note that since the lens of the eye lets water through, if blood sugar concentrations vary a lot, the lens of the eye will shrink and swell with fluid accordingly. As a result, blurry vision is very common in poorly controlled diabetes. Patients are usually discouraged from getting a new eyeglass prescription until their blood sugar is controlled. This allows for a more accurate assessment of what kind of glasses prescription is required.
