Some issues Dr. Clare Elizabeth Moynihan, MD can help you with:

Kidney Stones

Kidney stones are hard deposits that form in the kidneys, made up of minerals that are normally present in urine. They can vary in size, from as small as a grain of sand to as large as a nickel, occasionally even larger. Sometimes they lodge in the kidney, and sometimes they break free and make their way out through the urinary tract, which can be extremely painful.

Kidney stones can be smooth or jagged and are yellow to brown in color. They are mostly comprised of the minerals calcium, oxalate, and phosphorus. Examining the stones to see what they are made of can show what caused the stone to be formed in the first place. For example, a stone made of mostly calcium, which is the most common type, can happen any time the urine becomes too concentrated due to dehydration or a blockage in the kidney. A uric acid stone forms when acid levels in the urine get too high, usually due to excessive consumption of animal protein such as meat and fish. A struvite stone is a sign of certain infections, and a cystine stone can be due to a genetic disorder that raises the risk of kidney stones.

The most common symptom of kidney stones is pain, either in the back or lower abdomen, or severe pain when urinating. There may also be blood in the urine. Treatment for kidney stones depends on how large the stone is. Very small stones can pass out of the body on their own, and they do not require treatment other than drinking adequate water and taking pain killers. Larger stones need to be broken apart and removed. The main treatment options are:

  • Shock wave lithotripsy, which uses sound wave vibrations to break apart the stone
  • Percutaneous nephrolithotomy, or the use of a very tiny tool (like a wire inserted through the back) to break apart and remove the stone
  • Ureteroscopy, a thin tube inserted through the urethra and bladder to the stone, where tiny tools can grasp the stone and remove

People who have had one kidney stone are at risk of developing another. To reduce this risk, patients are given instructions specific to the type of stone they developed. Generally the instructions will include drinking more water to dilute the urine, but it may also involve lowering sodium intake or eating less meat.

Polycystic Ovary Syndrome (PCOS)

Polycystic ovarian syndrome is a common endocrine disorder that causes symptoms such as acne, facial hair, and weight gain. It is often diagnosed when patients experience problems getting pregnant, because PCOS can interfere with ovulation. There is no cure for PCOS, but there are effective treatments that can lessen the severity of the symptoms.

Despite the name, not everyone with polycystic ovarian syndrome develops cysts on their ovaries. It is also possible to have ovarian cysts without having PCOS. The symptoms of polycystic ovarian syndrome are actually related to insulin resistance, a condition where the insulin made by the body is not effectively recognized by the cells. This causes the pancreas to release higher levels of insulin in order to keep blood sugar levels stable, and the excess insulin interferes with hormone production in the pituitary and ovaries, causing the PCOS symptoms.

The symptoms of PCOS include:

  • Weight gain
  • Acne
  • Facial or body hair
  • Thinning head hair
  • Missing or irregular periods
  • Infertility

PCOS is a syndrome, which means that if patients have PCOS, they might not have each and every symptom. Even a few of them might be enough to have physicians check for polycystic ovarian syndrome. A doctor might perform an exam and order blood tests to measure hormone levels.

Treatment for PCOS may include:

  • Insulin sensitizers, which help the body use insulin more effectively, lowering hormone levels. The most commonly used insulin sensitizer is metformin.
  • Weight loss. Being overweight does not cause PCOS, and PCOS can make losing weight difficult. Still, weight loss can improve symptoms for many women.
  • Birth control pills to regulate menstruation and sometimes reduce symptoms such as acne.
  • Fertility medications, especially medications to stimulate ovulation such as clomiphene.
  • Anti-androgen medications, which work to treat symptoms such as acne and facial hair.
  • Low-carb diets, which work similarly to insulin sensitizers to lower hormone levels and help reduce weight.
  • Ovarian drilling or resectioning, surgical procedures sometimes performed if infertility is a persistent problem. These procedures open up the wall of the ovary to temporarily make ovulation more likely.

Polycystic ovarian syndrome is one of the most common endocrine disorders affecting women. Left untreated, it can increase the risk of diabetes, heart disease, and certain cancers. Fortunately there are many good treatment options available.

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.

My son was never able to see Dr. Moynihan. He was registered as a new patient with Stanford Medical, but wasn't allowed to make an appointment with Dr Moynihan without specific lab work. His prior endocrinologist sent my son's medical records which included the lab work requested to Dr Moynihan's office, but they wouldn't accept that lab work due to it being just over the 3 month time period that they required. The Stanford office was useless in helping my son find a way to get the labwork done that they required and my son wasn't able to get the labwork done without a Dr's referrel, so we were caught in a Catch 22 not being able to get what Stanford required, but they not assisting in any reasonable way.
