Some issues Dr. Pericles F. Xynos, MD can help you with:

Cesarean Section (C-Section)

A Cesarean section (more often known as "C-Section") is a surgery performed during labor and delivery. A C-Section is a procedure that delivers a baby through an incision in the lower abdomen and uterus. In the United States, about a third of all births are performed by Cesarean section. Most often, a C-section is done by an obstetrician/gynecologist (OB-GYN), or in certain regions, a general surgeon or family physician.

C-section incisions can be up-and-down (vertical), from belly button to lower abdomen or side-to-side (horizontal), across the lower abdomen. Side-to-side incisions are more frequently used. After the exterior incisions are made, the doctor then cuts into the uterus and amniotic sac and delivers the infant and cuts the baby's umbilical cord. The mother receives medicine to expel the placenta and the doctor helps to safely remove it. Finally, the doctor uses sutures to seal the uterus and tissue incisions. The initial C-section skin incision is also closed with sutures or staples.

C-sections are typically performed with regional anesthesia, which inhibits pain in the lower half of the body, but allows mothers to be awake. However, some mothers may receive general anesthesia, where they are put to sleep during the surgical procedure.

C-sections may be planned or unplanned, depending on the circumstances of the birth.

Pre-existing conditions like heart disease, high blood pressure, herpes, and HIV may prompt a doctor to prescribe a C-section. Other situations for C-section include:

A large baby or birth to multiple children
Pelvic fracture or limited birth canal
Baby in the "breech position," where a baby is positioned feet or bottom first in the uterus
Baby with a developmental disorder
Irregular fetal heartbeat
Mother with a history of previous C-sections

Other mothers may require a C-section due to complications arising during delivery. These unplanned, emergency C-sections allow for a healthy birth even when complex complications are present. Problems during labor which may necessitate a C-section include:

Labor not progressing
Fetus switching position during labor
Distressed infant
Blockage of the cervical opening by the placenta
Prolapsed umbilical cord

Mothers should expect about a six-week recovery period following a C-section, including an initial hospital stay of two to three days. While in the hospital, mothers may spend time with their baby and begin breastfeeding. After returning home, mothers should limit strenuous activities such as lifting, reaching, and exercise, and should make sure to get plenty of rest.

Hysteroscopy

A hysteroscopy is a diagnostic procedure performed to examine the inside of the uterus. A thin tube with a camera and light at the end, called a hysteroscope, is inserted through the vagina. It allows the physician to view the cervix and uterine walls. Sometimes, gas or liquid is used to expand the uterus and allow a better view. If necessary, tiny instruments can also be passed through the tube and used for certain procedures, such as taking a biopsy or removing a polyp.

Hysteroscopy is often done to figure out the cause of abnormal menstrual bleeding. However, it can also be used to:

Identify the cause of recurrent miscarriage
Remove polyps or fibroids, non-cancerous growths in the uterus
Remove adhesions, scar tissue within the uterus
Identify uterine septums, a wall of tissue dividing the uterus
Perform ablation, the removal of excess uterine lining

If surgery is necessary, hysteroscopy is often used along with laparoscopy, a kind of surgery performed through small incisions in the abdomen. Tiny tools are passed through the incisions, and the hysteroscope guides the doctors while surgery is performed.

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.
