Some issues Dr. John J. Mast, MD can help you with:

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 Attack

A heart attack is a serious medical event that happens when the blood supplying oxygen to the heart is cut off, usually because of a blockage in an artery. This results in damage or death of part of the heart muscle. The heart can heal, but like any part of the body that was injured it leaves a scar. This scar tissue does not contract effectively, so the ability of the heart to pump is lowered after a heart attack.

A heart attack, sometimes called a myocardial infarction, can happen without warning. However there are certain factors that raise the risk of heart attack. Some of these are:

Age
Gender (most heart attack sufferers are male)
A family history of heart attacks
Smoking
Obesity
High cholesterol
High blood pressure
Diabetes
Unhealthy lifestyle choices (lack of exercise, poor diet, too much alcohol or stress)

Heart attacks typically feel like pain or pressure in the chest that can radiate out to the back, arm, or jaw. Some other symptoms can include fatigue or weakness, shortness of breath, sweating, and nausea.

Treatment aims to increase blood flow to the heart muscle by opening up blocked blood vessels. Medications are sometimes used to dissolve clots in the arteries. Aspirin and other medications such as Plavix can thin the blood and make clots less likely to form. Dilators can widen blood vessels to make room for more blood to flow. Doctors can also use a procedure called catheterization to look at the blood vessels around the heart directly, place stents, or widen vessels using angioplasty. In extreme cases bypass surgery can be used to help blood flow better. After recovery, it is important to lead a healthy lifestyle and take any prescribed medications in order to protect the heart.

Thyroid Problems

Thyroid problems are a group of conditions that alter hormone regulation and metabolism. The thyroid is a small, butterfly-shaped gland located in the lower neck, just below the Adam's apple (laryngeal prominence) and larynx (voice box). Despite its small size, the thyroid has an outsized effect on the body by regulating hormones that control metabolism. Metabolism is the body's process of converting consumed food into fuel to power the entire body. Heart rate, weight, cholesterol, body temperature, and even physical growth and development are all affected by the metabolism.

When the thyroid malfunctions, the body is unable to properly process and allocate energy. Thyroid problems, such as hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid), cause irregular metabolism. In some cases, the body produces antibodies that attack the thyroid cells for unknown reasons. The damaged thyroid responds by releasing either too little or too much T3 and T4 thyroid hormones. Thyroid malfunctions may also arise from genetic causes or iodine deficiency. Thyroid problems may include:

Hashimoto's thyroiditis, an autoimmune disease that causes hypothyroidism
Graves' disease, an autoimmune disease that causes hyperthyroidism
Goiter
Thyroid nodule
Thyroid cancer

Hashimoto's is the leading cause of hypothyroidism, which is when the thyroid does not produce enough hormones to stimulate adequate metabolism. The condition is diagnosed by blood tests that measure TSH (thyroid stimulating hormone) and detect Hashimoto's antibodies. Symptoms of hypothyroidism include sluggish metabolism, inflammation, fatigue, weight gain, brittle hair, dry skin, and sensitivity to cold. To supplement impaired thyroid function, patients with Hashimoto's are typically prescribed synthetic thyroid hormone pills. Such patients may need to consume synthetic thyroids for the rest of their lives. Other treatments may include dietary changes, such as the avoidance of certain foods and medication to reduce inflammation. Frequent blood tests can inform patients if their TSH levels are within a normal range.

Grave's disease is most frequently the cause of hyperthyroidism, which is when the thyroid produces too many hormones, overstimulating one's metabolism. The condition is also diagnosed by blood tests that measure TSH and detect Grave's antibodies. Elevated heart rate, high blood pressure, sweating, bulging eyes, and weight loss are common symptoms of hyperthyroidism. Treatments for hyperthyroidism include oral radioactive iodine, which slowly shrinks the thyroid, slowing the production of excess thyroid hormone. Other anti-thyroid medications such as methimazole (Tapazole) also reduce the production of thyroid hormones. Blood pressure medications known as beta blockers can ease the increased heart rate caused by hyperthyroidism. If treatments are unsuccessful, patients may be prescribed a thyroidectomy, or surgery to remove part or all of the thyroid. Some patients with hyperthyroidism may require ophthalmological (eye medicine) treatments such as eye drops, prednisone, and surgery to reduce eye swelling and bulging.

Untreated thyroid disorders frequently lead to goiters or thyroid nodules. A thyroid goiter is a large lump that can be felt near the base of the neck and is made of swollen thyroid tissue or nodules (excess cell growth). Nodules and goiters are diagnosed by CT scan or ultrasound. Obstructive goiters can cause pain, coughing, and abnormal breathing. The most common cause of goiters is hyperthyroidism (overactive thyroid). However, Hashimoto's is also known to cause goiters or nodules. Goiters develop from continued damage from antibodies to the thyroid over time. At times, a goiter can result from a cancerous thyroid tumor. Most goiters and nodules are themselves benign.

The exact causes of thyroid cancer are unknown. People who develop thyroid cancer may or may not have another thyroid problem such as Hashimoto's or Grave's disease. Symptoms of thyroid cancer include a nodule that can be felt on the neck, hoarseness, difficulty swallowing, swelling in the neck, and neck and throat pain. CT and MRI scans are used to diagnose thyroid cancer. There are four types of thyroid cancer which vary in intensity. Thyroidectomy (thyroid removal surgery) is usually prescribed to treat thyroid cancer.

Thyroid problems are often long-term conditions that require some form of treatment. With regular monitoring and medication, many people with thyroid problems are able to lead active and fulfilling lives.
