Some issues Dr. John David Knight, MD can help you with:

Heart Problems

The heart is one of the most important organs in the body. This smooth muscle expands and contracts rhythmically an entire lifetime, pumping blood to the lungs and then to every other cell in the body. When heart problems occur, it becomes difficult for the body to get the nutrients and oxygen it needs via the blood. So while there are a variety of illnesses and disorders that affect the heart, most of them cause weakness, exhaustion and shortness of breath. The most common heart conditions include heart disease, angina, arrhythmia, and valve disorders.

Heart disease is the leading cause of death in the United States for both men and women. This includes coronary artery disease, heart attacks, congestive heart failure, and congenital heart disease. Some conditions, such as genetics, cannot be controlled. But there are many other things one can do to lower their risk for heart disease. Controlling high blood pressure and cholesterol levels, reducing or stopping smoking, exercising more and losing weight if needed, and eating a diet low in sodium can all protect the heart.

Angina is a squeezing type of chest pain that happens when the muscles around the heart don't get enough oxygen. It can be regular or infrequent. Usually, angina is caused by coronary heart disease. However, not all chest pain is angina. Chest pain can also be caused by a lung infection or panic attack, for example, so it is important to have any sudden pain checked.

Arrhythmia is the word for when the heart beats too fast, too slow, or irregularly with skipped beats. It can feel frightening, and depending on the type it can be dangerous, but in most cases arrhythmia is not serious and can be treated. It is very common, especially in older adults.

Heart valve problems can happen in any one of the the heart's four valves that keep blood flowing where it needs to go. Babies can be born with problems in their heart valves, or valves can be damaged by infections. The valves can stiffen and become less mobile, or they can stop closing properly and 'leak' when the heart beats. Valve problems can usually be repaired surgically.

Urinary Tract Infection (UTI)

A urinary tract infection, or UTI, happens when bacteria enter the body through the opening where urine is normally released. The bacteria infect the lining of the urethra and bladder, turning them red and inflamed. This causes pain in the abdomen or pelvic area, a burning sensation during urination, a sense of urgency about going to the bathroom, frequent urination, and urine that smells bad and looks cloudy, or even contains traces of blood. If the urinary tract infection is severe, it may travel all the way to the kidneys, a more serious kind of UTI called pyelonephritis. Patients with this kidney infection might have blood in their urine, feel back pain, and develop a fever.

Urinary tract infections are extremely common: 12% of all men and 40-50% of all women will have a urinary tract infection during their lifetime. They are more common in women because women have shorter urethras, so bacteria have a shorter distance to travel from the outside of the body to the bladder and cause an infection. Some people also have urethras that are an unusual shape or have an obstruction in the urethra that makes getting a UTI more likely. Also, certain chronic illnesses like diabetes weaken the immune system, so any bacteria in the body are more likely to cause an infection.

A urinary tract infection can be diagnosed very quickly by a doctor. A sample of urine can be examined under a microscope for the presence of bacteria or white blood cells. There are also diagnostic strips that can be used to test a urine sample without the need for a microscope. Once a diagnosis is made, treatment is a course of oral antibiotics, and most patients feel better within just a few days. There are some things that patients can do themselves to help reduce the risk of getting a urinary tract infection in the future. Stay well hydrated, wipe from front to back after going to the bathroom, wear breathable cotton undergarments, and don't hold it in when patients feel the urge to go.
