Once the diagnosis of hypertension has been made, healthcare providers should attempt to identify the underlying cause based on risk factors and other symptoms, if present. Secondary hypertension is more common in preadolescent children, with most cases caused by kidney disease. Primary or essential hypertension is more common in adolescents and has multiple risk factors, including obesity and a family history of hypertension. Laboratory tests can also be performed to identify possible causes of secondary hypertension, and to determine whether hypertension has caused damage to the heart, eyes, and kidneys. Additional tests for diabetes and high cholesterol levels are usually performed because these conditions are additional risk factors for the development of heart disease and may require treatment.
Recent research indicates prolonged chronic stress can contribute to metabolic syndrome by disrupting the hormonal balance of the hypothalamic-pituitary-adrenal axis (HPA-axis). A dysfunctional HPA-axis causes high cortisol levels to circulate, which results in raising glucose and insulin levels, which in turn cause insulin-mediated effects on adipose tissue, ultimately promoting visceral adiposity, insulin resistance, dyslipidemia and hypertension, with direct effects on the bone, causing "low turnover" osteoporosis. HPA-axis dysfunction may explain the reported risk indication of abdominal obesity to cardiovascular disease (CVD), type 2 diabetes and stroke. Psychosocial stress is also linked to heart disease. http://www.sandysidhumedia.com/wp-content/uploads/2012/12/nailahquote.png
As you lose weight your leptin levels drop, signalling to your body that it should probably start to slow things down. In this case you can feel hungry all of the time, but also sluggish and weight loss stops. Some people even see weight gain which can either send you into frustration nation… or alternatively lead you to cut more calories and drive your metabolic rate and gut hormone signalling down even further! Yikes!
The exact cause of metabolic syndrome is unknown. It is frequently influenced by diet and lifestyle, but also seems to be genetically driven. As stated, many features of metabolic syndrome are associated with “insulin resistance,” which causes cells to lose their sensitivity to insulin, the hormone needed to allow blood sugar to enter cells for use as fuel. As glucose levels in the blood increase, the pancreas tries to overcompensate and produce even more insulin, which ultimately leads to the characteristic symptoms of metabolic syndrome. When insulin levels spike, a stress response occurs that leads to elevations in cortisol, the body’s long-acting stress hormone. This in turn creates an inflammatory reaction that if left unchecked begins to damage healthy tissue.
Diabetes is a chronic, metabolic disease characterized by elevated levels of blood glucose (or blood sugar), which leads over time to serious damage to the heart, blood vessels, eyes, kidneys, and nerves. The most common is type 2 diabetes, usually in adults, which occurs when the body becomes resistant to insulin or doesn't make enough insulin. In the past three decades the prevalence of type 2 diabetes has risen dramatically in countries of all income levels. Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin by itself. For people living with diabetes, access to affordable treatment, including insulin, is critical to their survival. There is a globally agreed target to halt the rise in diabetes and obesity by 2025.

Various expert groups have produced guidelines regarding how low the blood pressure target should be when a person is treated for hypertension. These groups recommend a target below the range 140–160 / 90–100 mmHg for the general population. Cochrane reviews recommend similar targets for subgroups such as people with diabetes and people with prior cardiovascular disease.
Type 1 and type 2 diabetes were identified as separate conditions for the first time by the Indian physicians Sushruta and Charaka in 400–500 CE with type 1 associated with youth and type 2 with being overweight. The term "mellitus" or "from honey" was added by the Briton John Rolle in the late 1700s to separate the condition from diabetes insipidus, which is also associated with frequent urination. Effective treatment was not developed until the early part of the 20th century, when Canadians Frederick Banting and Charles Herbert Best isolated and purified insulin in 1921 and 1922. This was followed by the development of the long-acting insulin NPH in the 1940s.
Apart from these medications, treating diabetes effectively means taking a well-rounded approach: You’ll need to eat well, exercise, and manage stress, because all these factors can affect your blood sugar levels. Staying healthy with diabetes also requires caring for yourself — like protecting your feet, practicing oral hygiene, and tending to your mental health.

So far, none of the hypotheses accounting for virus-induced beta cell autoimmunity has been supported by stringent evidence in humans, and the involvement of several mechanisms rather than just one is also plausible.
Although treatment of sleep apnea with continuous airway positive pressure (CPAP) would logically seem to improve CV outcomes and hypertension, studies evaluating this mode of therapy have been disappointing. A 2016 review of several studies indicated that CPAP either had no effect or a modest BP-lowering effect.  Findings from the SAVE study showed no effect of CPAP therapy on BP above usual care.  It is likely that patients with sleep apnea have other etiologies of hypertension, including obesity, hyperaldosteronism, increased sympathetic drive, and activation of the renin/angiotensin system that contribute to their hypertension. Although CPAP remains an effective therapy for other aspects of sleep apnea, it should not be expected to normalize BP in the majority of patients.

"Secondary" diabetes refers to elevated blood sugar levels from another medical condition. Secondary diabetes may develop when the pancreatic tissue responsible for the production of insulin is destroyed by disease, such as chronic pancreatitis (inflammation of the pancreas by toxins like excessive alcohol), trauma, or surgical removal of the pancreas.
To measure your blood pressure, a specialist places an inflatable cuff around your arm and measures your blood pressure using a pressure-measuring gauge. A blood pressure reading, as shown in the blood pressure monitor in the image, measures the pressure in your arteries when your heart beats (systolic pressure) in the first number, and the pressure in your arteries between heartbeats (diastolic pressure) in the second number.
Eating healthfully. The Dietary Approaches to Stop Hypertension (DASH) diet and the Mediterranean diet, like many healthy-eating plans, limit unhealthy fats and emphasize fruits, vegetables, fish and whole grains. Both dietary approaches have been found to offer important health benefits — in addition to weight loss — for people who have components of metabolic syndrome.
Great article, Roman. I bought LWF2 as soon as I saw that it was released. Typically, sequels are not as good as the first, but I knew Jen's would be the exception and she did not let me down! :) I have seen others ask about your manual if we have already invested in LWF2. How should we go about this? Shall we send you the order number or will it be uploaded to the LWF2 member site in the download section? Cheers and thanks for such epic content!
For a diagnosis of metabolic syndrome, a child must have at least three of the four risk factors. The most common risk factors in teens are hypertension and abnormal cholesterol. Even when just one risk factor is present, a doctor will likely check for the others. This is especially true if a child is overweight, has a family member with type 2 diabetes, or has acanthosis nigricans.
I hate to burst anyone's bubble, but doing 5-10s intervals probably isn't going to do much for you – unless you're doing a ton of them, or using really short rest intervals. Essentially, you have to get to the point where you shift over from the ATP-PC to the glycolitic (anaerobic) system. This is a sweet spot where intensity of exercise is high while volume remains up – and that's how you create the "metabolic debt" that makes interval training so beneficial.

Researchers assigned overweight subjects to three groups: diet-only, diet plus aerobics, diet plus aerobics plus weights. The diet group lost 14.6 pounds of fat in 12 weeks. The aerobic group lost only one more pound than the diet group. Their training was three times a week starting at 30 minutes and progressing to 50 minutes over the 12 weeks. Nothing special. But the weight training group lost over 21 pounds of fat. That's 44% and 35% more than diet and cardio-only groups respectively. The addition of aerobic training didn't result in significant fat loss over dieting alone. Thirty-six sessions of up to 50 minutes is a lot of work for one additional pound of fat loss. But the addition of resistance training greatly accelerated fat loss results.
Tips for Success: Read your labels. Watch out for hidden carbs; to calculate the grams of carbs that impact your blood sugar, subtract the number of grams of dietary fiber from the total number of carb grams. Also double-check serving sizes on labels; some foods and drinks are actually two or more servings, so you need to add in those extra carbs and calories.
When a blood pressure reading is taken, the higher number represents the systolic pressure and the lower number represents the diastolic pressure. For example: 120/80 (120 over 80) in an adult means that the systolic pressure is 120 and the diastolic pressure is 80. As kids grow, their blood pressure increases from a systolic pressure of about 70–90 (as babies) to adult values (when they're teens).
The key sign of metabolic syndrome is central obesity, also known as visceral, male-pattern or apple-shaped adiposity. It is characterized by adipose tissue accumulation predominantly around the waist and trunk. Other signs of metabolic syndrome include high blood pressure, decreased fasting serum HDL cholesterol, elevated fasting serum triglyceride level, impaired fasting glucose, insulin resistance, or prediabetes. Associated conditions include hyperuricemia; fatty liver (especially in concurrent obesity) progressing to nonalcoholic fatty liver disease; polycystic ovarian syndrome in women and erectile dysfunction in men; and acanthosis nigricans.
At the end of the twelve-week study both groups lost weight, but the difference in the amount of muscle vs. fat loss was telling. The aerobic group lost 37 pounds over the course of the study. Ten of those pounds came from muscle. In contrast, the resistance-training group lost 32 pounds. None of the weight they lost came from muscle. When the resting metabolic rate of each group was calculated, the aerobic group was shown to be burning 210 fewer calories per day. The resistance-training group avoided this metabolic decline and instead was burning 63 more calories per day.
