High Blood Pressure (Hypertension) Signs, Causes, Diet, and Treatment
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms. Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure. The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater. If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.REFERENCE: CDC. High Blood Pressure. Updated: Nov 13, 2017.
Multiple Sclerosis (MS) Symptoms, Causes, Treatment, Life Expectancy
Multiple sclerosis or MS is an autoimmune disorder in which brain and spinal cord nerve cells become demyelinated. This damage results in symptoms that may include numbness, weakness, vertigo, paralysis, and involuntary muscle contractions. Different forms of MS can follow variable courses from relatively benign to life-threatening. MS is treated with disease-modifying therapies. Some MS symptoms can be treated with medications.
Cystic fibrosis is a disease of the mucus and sweat glands. Cystic fibrosis is an inherited disease. The outcome of the disease leaves the body malnourished, with bulky and fouls smelling stools, vitamin insufficiency, gas, painful or swollen abdomen, infertility, susceptible to heat emergencies, and respiratory failure. There is no cure for cystic fibrosis, treatment of symptoms is used to manage the disease.

Multiple Sclerosis (MS)
Multiple sclerosis (MS) symptoms vary from person to person, and can last for days to months without periods of remission. Symptoms of MS include sexual problems and problems with the bowel, bladder, eyes, muscles, speech, swallowing, brain, and nervous system. The early symptoms and signs of multiple sclerosis usually start between age 20 and 40. MS in children, teens, and those over age 40 is rare. Treatment options for multiple sclerosis vary depending on the type and severity of symptoms. Medications may be prescribed to manage MS symptoms.
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Learn about osteoporosis, a condition characterized by the loss of bone density, which leads to an increased risk of bone fracture. Unless one experiences a fracture, a person may have osteoporosis for decades without knowing it. Treatment for osteoporosis may involve medications that stop bone loss and increase bone strength and bone formation, as well as quitting smoking, regular exercise, cutting back on alcohol intake, and eating a calcium- and vitamin D-rich balanced diet.
Skin cancers occur when skin cells undergo malignant transformations and grow into tumors. The most common types of skin cancer, basal cell carcinoma and squamous cell carcinoma, are highly curable when they are diagnosed and treated early. Sun exposure, tanning beds, depressed immune system, radiation exposure, and certain viral infections are risk factors for skin cancer. Skin cancers are treated with surgery or radiation. The prognosis of nonmelanoma skin cancers is generally very good.
Fatty Liver (NASH)
Nonalcoholic fatty liver disease or NASH occurs due to the accumulation of abnormal amounts of fat within the liver. Fatty liver most likely caused by obesity and diabetes. Symptoms of fatty liver disease are primarily the complications of cirrhosis of the liver; and may include mental changes, liver cancer, the accumulation of fluid in the body (ascites, edema), and gastrointestinal bleeding. Treatment for fatty liver includes avoiding certain foods and alcohol. Exercise, weight loss, bariatric surgery, and liver transplantation are treatments for fatty liver disease.
Rickets is caused by a deficiency of vitamin D, calcium, or phosphate. Infants and children who are exclusively breastfed, have dark skin, and infants born to mothers who are vitamin D deficient are most at risk for developing rickets. Symptoms and signs of rickets include bone pain, delayed teeth formation, short stature, skeletal deformities (bowlegs, abnormally shaped skull), and decreased muscle strength. Treatment of rickets depends upon the cause, but the first step usually involves correcting any abnormal levels of calcium, phosphate, or vitamin D with supplements.
Cancer Risk Factors
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
Erectile Dysfunction (ED, Impotence)
Erectile dysfunction (ED, impotence) is the failure to achieve or maintain an erection. There are many potential underlying causes of erectile dysfunction, including stress and emotional problems, brain dysfunction, problems with blood supply to the penis, and structural problems with the penis. Erectile dysfunction is diagnosed by taking the patient's history and physical exam. Blood tests measuring kidney function and blood sugar, cholesterol, hormone, and prostate-specific antigen (PSA) levels may be ordered. Urinalysis, ultrasound, and other more sophisticated tests may be required. The treatment of erectile dysfunction depends on the underlying cause. Medications, penile injections, penile implants, and vacuum devices may be used. Treatment for erectile dysfunction is usually successful. The patient should manage heart disease risk factors (high blood pressure, high cholesterol, diabetes) as they are related to erectile dysfunction risk.
Celiac disease is a condition in which a person has inflammation of the small intestinal mucosa when exposed to gluten in the diet. Symptoms of celiac disease include bloating, nausea, diarrhea, and abdominal discomfort. Treatment is a gluten free diet. Some individuals may have refractory celiac disease in which they do not respond to a gluten free diet.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
Vitamin D Deficiency
Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors. Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
Vitamins and Calcium Supplements
Vitamins are organic substances that are essential for the proper growth and functioning of the body. Calcium is a mineral essential for healthy bones and is also important for muscle contraction, heart action, and normal blood clotting.

Primary Biliary Cirrhosis Treatment (PBC)
Primary biliary sclerosis (PBC) is thought to be an autoimmune disorder that involves the deterioration of the liver's small bile ducts. These ducts are crucial to transport bile to the small intestine, digesting fats and removing wastes. Symptoms of PBC are: Edema Itching Elevated cholesterol Malabsorption of fat Liver cancer Gallstones Urinary tract infections (UTIs) Hypothyroidism Treatments include ursodeoxycholic acid (UDCA); colchicine (Colcrys); and immunosuppressive medications, such as corticosteroids; obeticholic acid (Ocaliva); and medications that treat PBC symptoms. For PBC that is associated with cirrhosis of the liver, liver transplantation may be indicated in extreme cases.
Asthma in Children
Asthma in children manifests with symptoms such as coughing and wheezing. Rates of asthma in children are increasing. Asthma in children is usually diagnosed based on the description of symptoms. Lung function tests may also be used. A variety of medications are used for the treatment of childhood asthma.
Sunscreens are crucial for sun protection. Sun damage to the skin from exposure to ultraviolet rays is a risk factor for skin cancer and melanoma. To avoid sunburn, people should limit sun exposure during the peak hours of 10 a.m. to 3 p.m., wear protective clothing, and use a sunscreen. People with sensitive skin should use a sunscreen with an SPF of 30 or more.
Vitamins & Exercise: Heart Attack Prevention Series
Vitamins and exercise can lower your risk for heart attack and heart disease. Folic acid, vitamins, and homocysteine levels are interconnected and affect your risk for heart disease or heart attack. For better heart health, avoid the following: fried foods, hard margarine, commercial baked goods, most packaged and processed snack foods, high fat dairy, and processed meats such as bacon, sausage, and deli meats. Antioxidants and exercise also play a key role in heart attack and heart disease prevention. Lower your risk factors for heart disease and heart attack by: lowering cholesterol, lowering blood pressure, diabetes prevention, and smoking cesssation. Here are a few things you can do to prevent heart attacks: Eat whole, natural, fresh foods, eat five to 10 servings of fruits and vegetables daily, eat more omega-3 fatty acids, drink water, tea, non-fat dairy and red wine, eat lean proteins, limit glycemic foods, and exercise daily.
