Low Blood Pressure (Hypotension)
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Obesity is the state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20% over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
How Long Is a Cold or Flu Contagious?
Viruses cause the common cold and the flu. Early symptoms and signs for a cold and the flu are similar, however, flu symptoms are typically more severe than cold symptoms. Cold and flu viruses are transmitted typically via coughing or sneezing.
The common cold (viral upper respiratory tract infection) is a contagious illness that may be caused by various viruses. Symptoms include a stuffy nose, headache, cough, sore throat, and maybe a fever. Antibiotics have no effect upon the common cold, and there is no evidence that zinc and vitamin C are effective treatments.
Asthma: Over the Counter Treatment
Patients who have infrequent, mild bouts of asthma attacks may use over-the-counter (OTC) medications to treat their asthma symptoms. OTC asthma medicines are limited to epinephrine and ephedrine. These OTC drugs are best used with the guidance of a physician, as there may be side effects and the drugs may not be very effective.
Myasthenia gravis, a chronic autoimmune neuromuscular disease. Varying degrees of weakness of the voluntary muscles of the body are the main characteristics. A defect in the transmission of nerve impulses of the muscles is the cause of myasthenia gravis. Myasthenic crisis is when the muscles that control breathing weaken, which requires immediate medical attention. Symptoms include weakness of the eye muscles, facial expression, and difficulty swallowing. Treatment of myasthenia gravis includes medical therapies to control the symptoms of the disease.
Lung Anatomy (Structure and Function)
The lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
Cold, Flu, Allergy Treatments
Before treating a cold, the flu, or allergies with over-the-counter (OTC) medications, it's important to know what's causing the symptoms, which symptoms one wishes to relieve, and the active ingredients in the OTC product. Taking products that only contain the medications needed for relieving your symptoms prevents ingestion of unnecessary medications and reduces the chances of side effects.
Weight Control and Smoking Cessation
One concern smokers have when considering quitting smoking is weight gain. Not everyone will gain weight when they stop smoking. There are lifestyle changes that can be made to avoid weight gain during smoking cessation. Lifestyle changes include regular exercise, proper nutrition, limiting snacking and alcohol, medication, and weight management counseling.
