Some issues Dr. Glenn R. Davis, MD can help you with:

Asthma

Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

Allergens (dust mites, pet fur, mold, pollen, grass)
Irritants (smoke, pollution, dust, chemicals)
Viral infections
Physical activity, especially outdoors
Certain medications or chemicals in foods (aspirin, sulfites)

Treatment for most asthma patients involves three steps. Patients learn what their asthma triggers are and avoid them. They take a daily control medication, usually an inhaled corticosteroid, to reduce inflammation in the lungs. Also, they have rescue medication with them at all times to take in case of a severe attack. These quick-acting inhaled medications relax the muscles around the airways and allow the lungs to open up for air.

There is no cure for asthma, but with treatment it should not interfere with daily life and activities.

Depression

Everyone knows what it feels like to get the blues once in a while. But depression is a serious illness that is more severe than a bad day and lasts much longer. Symptoms of depression stop a person from being able to function and enjoy daily activities for weeks or months at a time. It can happen to anyone, and it isn't something that people can control by force of will or "snap out of it."

Some common symptoms of depression include:

Feeling sad, guilty, empty or hopeless
Fatigue and a lack of energy and motivation
A loss of pleasure in activities that were previously enjoyed
Unusual sleep or eating habits
Mental fog -- trouble concentrating, remembering, or making decisions
Physical aches and pains
Suicidal thoughts or a preoccupation with death

We don't yet know what causes depression, but it's thought that it is a combination of genetic, biological, environmental, and social influences. Because of this, the most effective treatments for depression combine medication with psychotherapy. Therapy, especially cognitive-behavioral therapy, can be extremely helpful in resolving the negative thoughts and feelings that come with depression. It gives patients new tools that they can use themselves to cope when their depression is making them feel down.

Some of the common medications used to treat depression include antidepressants such as SSRI's (Prozac, Paxil, Zoloft) or atypical antidepressants (Cymbalta, Wellbutrin). It's important to remember that these medications have different effects on everybody, and no one medication works right for everyone. Patients may have to try a couple before finding the one that works just right for them. If the first medication they try doesn't work, they should talk to their doctor about trying something else. In extreme cases where medication is not enough, electro-convulsive therapy and hospitalization may be the answer to keeping a severely depressed person safe.

Depression is a difficult illness to deal with, but it is more common than believed and there are many people who can help. With the right treatment, individuals with depression can get back to fully enjoying life again.

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.

I was trying to make an appointments as a new patient. Left a voicemail and once the call was returned the person asked what employer I was with.. once explained that I was a new patient and I was following the recommended providers from my insurance , she automatically told me that David not even Dr.. was not accepting new patients.
This is ridiculous and unprofessional!
I would not recommend this facility at all!

Overall Rating: 5.0 2019-07-12

This office has been good for us.  The previously mentioned supplements - we don't feel they push the supplements.  Dr. Davis told me on first visit he likes certain supplements but  we were never pushed into them.  We do see the PA a lot (Melinda) but she has been very caring, detail-oriented, and she has never rushed us.
