Mr. John B. Monaco M.D.'s Expert Contributions
  • Is Metformin a lifelong medicine?

    Usually not. Sometimes after pregnancy, ovarian function returns to normal. Certainly after menopause, PCOS is no longer an issue. READ MORE

  • Can a green color on a sanitary pad indicate infection?

    Yes, it can. Even if you have no symptoms, I would have your GYN check for an infection such as Trichomonas or a bacterial vaginosis. READ MORE

  • My delayed period

    At your age, the most likely cause is stress which can interfere with the normal Brain-Pituitary-Ovarian function. Low body weight, poor nutrition and intense exercise can also affect the menstrual cycle. While most GYN's would put you on the birth control pill, I prefer not to use OCP's. Rather cycling you on progesterone (not a progestin) works nicely to regulate your cycle and provides the many benefits of progesterone without shutting down your system which happens with the BCP. READ MORE

  • What are ways to deal with menopause?

    If she is still menstruating, cycling with compounded bioidentical progesterone can be like a miracle. I have my compounding pharmacist make 50mg SR capsules and my patients take it from day 12 -26 of their cycle (1st day of flow is day #1) 1cap x5 days, 2x5, 3x5. If no mense occurs, this may be the first sign that you are menopausal. Your GYN or a doctor specializing in natural hormone replacement can help. READ MORE

  • How is chlamydia usually treated?

    Antibiotic therapy is the primary treatment usually with either tetracycline or erythromycin. Some other newer antibiotics may be used. Correct treatment and prevention is the key. Have your partner checked and treated as the male, especially if uncircumcised, can keep re-infecting you. READ MORE

  • I masturbated and I am now suffering from urine incontinence. Are the two related?

    There is no known association of masturbation and urinary incontinence unless you have used "toys" which can irritate the urethral opening from the bladder and can give symptoms like a UTI which may cause some urinary leakage. If you have symptoms like urgency, burning and frequency you should have a urinalysis done. READ MORE

  • If I am planning to conceive by next year should I start folic acid tablets?

    You can start folic acid supplements anytime, especially if you have a mutation of one of the genes that activates folic acid, which is quite common. The only concern with a mutation is that you may need to take a slightly higher dose of folate and may need the activated form L-5 MTHF, which you can purchase in most vitamin shops. Folic acid is important before conception to reduce neural tube defects. The usual dose in pregnancy is 1mg daily, the RDA in non-pregnancy is .4mg. There is a simple lab test that will check for this mutation. Check with your insurance company first to make sure they will cover this. READ MORE

  • What are the long term side effects of consuming Primordial N tablets?

    I would absolutely not take this medication. It is a synthetic progestin and not progesterone. Progestins have been shown to cause multiple issues including an increase in blood clotting, heart and possibly stroke issues and an increase in breast cancer. These progestins are often incorrectly referred to as progesterone which they are not. They are modifications of the progesterone molecule. Naturally formulated bioidentical progesterone cannot be patented and therefore, pharmaceutical companies must change the molecule in order to get a patent. In my practice, I use progesterone which can be obtained by prescription in your local drug store as Prometrium or it can be compounded by a compounding pharmacist, which is what I do. READ MORE

  • Will my pregnancy leg pain get better after delivery?

    Generally, the leg pain improves dramatically after delivery. This pain is usually due to several factors: change in the curvature of the spine (lordosis of pregnancy), loosening of the ligaments of the pelvis, pressure of the enlarging fetus on the pelvic bones and nerves and muscle relaxation all (except the lordosis) a result of high levels of progesterone. READ MORE

  • Can pregnancy cause changes in heartbeat?

    It could be, but this is something that you need to discuss with your Obstetrician who may want you evaluated to rule out a more serious condition of the heart. Often, the stress of pregnancy will bring out an underlying condition and pregnancy is especially stressful on the cardiovascular system with many significant changes that occur. Usually a young healthy woman will have no issues. READ MORE

  • I have had 2 ectopic pregnancies. I want to concieve again. How can I prevent another one?

    Having 2 consecutive ectopic pregnancies is very unusual in a woman with a normal pelvis. You need to discuss with your gynecologist some of the possible causes such as endometriosis, pelvic infection, adhesion, and genetic anomalies of the pelvic organs. If not already done, a laparoscopic evaluation of pelvis could be done (you likely had this done to treat the ectopics, but a repeat exam may be helpful to assess things in the non-pregnant state and dye can be instilled into the uterus during the procedure to assess the patency of the fallopian tubes. When you do get pregnant, closely following blood levels of the pregnancy hormone Beta HCG and ultrasounds can help to pick up another ectopic early when minimally invasive treatment can remove the ectopic and lessen any scarring of the tubes. There is really nothing that you can take or do to prevent ectopics. It's most likely a structural issue affecting tubal patency and function. READ MORE

  • What causes sudden thick white discharge?

    The hormonal fluctuations commonly seen in menopause often start in the mid 30's. This may be the issue but infections such as yeast, trichomonas and bacterial infections, although unlikely, should be ruled out. While the discharge associated with these conditions is different, I have seen all of them in patients with a non specific white discharge. Your gynecologist can do a simple office exam and microscopic exam. READ MORE

  • Do I have genital warts or herpes

    The only way to tell for sure is to have your gynecologist do an evaluation which may mean visual inspection, perhaps colposcopic or microscopic inspection, culture or even biopsy. READ MORE

  • What can I do to prevent my vaginal infection from recurring?

    A thorough exam by your gynecologist with accurate diagnosis and specific treatment is the only way to correctly identify the type of infection and eradicate it with the correct treatment. READ MORE

  • I had unprotected sex with my fiance. How can I make sure there is no pregnancy?

    Unfortunately, it becomes a waiting game. You can get a pregnancy test in your local pharmacy. These tests have become quite sensitive and accurate. There is no natural way to prevent pregnancy after the fact. The morning after pill is most effective in the first 24-72 hours after intercourse. READ MORE

  • Does metformin increase my chances of getting pregnant?

    Metformin is often used to treat the insulin resistance commonly seen in patients with PCOS. It is more likely that that may increase fertility by addressing the metabolic process in the ovary. READ MORE

  • Despite of following my ovulation calendar I am not pregnant. Why?

    That is a question that can have many answers. Your gynecologist can discuss them with you and may refer you to a reproductive endocrinologist (a gynecologist specializing in infertility). Some possibilities include endometriosis, pelvic infections, blocked fallopian tubes, the male factors low sperm count, low motility and a varicocoel. The most important factor is stress, so patience with the process is important. 80% of women will conceive within 1 year assuming they have intercourse 2-3 times per week. Having sex more than that usually results in depletion of the males sperm count and can actually prolong the process. If you have none of the female issues and have discussed it with your GYN, then relax and enjoy the process. If you have any of those issues then He/She can begin to address them. READ MORE

  • menstruation

    The best thing that you did was to stop the injectable synthetic progestin contraceptive. Perimenopausal hormonal changes can begin as early as 30. Fluctuations in estrogen levels and declining levels of progesterone usually result in the many symptoms often seen, menstrual changes, frequent and heavy periods, depression, anxiety, sleep issues, moodiness, etc. You are basically on an hormonal roller coaster. I treat my patients with cyclic bioidentical progesterone (not provera, medroxy progesterone acetate of birth control pills). You need progesterone to balance the estrogen spikes, improve sleep, reduce anxiety and depression and protect both the breasts and endometrium (uterine lining). Of course, you should always rule out pregnancy. Natural progesterone will not adversely affect the fetus if you are pregnant and will increase your fertility, so if you go this route make sure that you are either accepting of a pregnancy or have another reliable method of contraception. You can usually find a doctor in your area that specializes in bioidentical hormone therapy or functional medicine. READ MORE

  • oligomenorrhea

    I am assuming that you are asking this for someone else, but light flow may be normal, due to low body weight and fat percentage, malnutrition, stress, intense exercise like marathon runners, etc. Of course, a pelvic exam should be done to rule out uterine anomalies and other structural issues. READ MORE

  • I had two periods cycles in one month. What could be wrong?

    This may just be a month where you had a shortened luteal phase, that is the follicle that forms after ovulation, the corpus luteum, and which makes progesterone may be short resulting in an early period. Pregnancy should always be ruled out. Depending upon your age, this may be the result of hormonal changes of perimenopause such as fluctuations of estrogen and falling levels of progesterone, the latter stabilizes the endometrium and prevents early breakdown and bleeding before the expect period. READ MORE

  • Is watery discharge a sign of pregnancy?

    Vaginal discharge, depending upon the characteristics of the discharge can signal anything from ovulation, infection, hormonal changes and pregnancy. Yes, you should consult with your GYN to make sure that there is no problem and to get peace of mind that this may be a normal healthy response. READ MORE

  • How can I manage my mood swings during pregnancy?

    Moodiness and irritability are quite common and the way a woman responds is very individualized. Sleep deprivation or interrupted sleep can often lower our boiling point so, if you can, concentrate of sleep and naps which means modifying your normal routine and letting some of your responsibilities go unattended. Calming therapies such as chamomile tea, meditation, etc may be helpful. While some calming herbs work well, their use in pregnancy is usually not advised due to lack of information about those herbs in pregnancy. It's difficult to evaluate herbs and drugs in pregnancy and most information is from animal studies. Adequate rest is still the best especially as the baby grows and causes more discomfort. READ MORE

  • I have missed my period and the pregnancy test is negative. What could be wrong?

    Perhaps nothing is wrong. A post ovulation ovarian cyst (corpus luteum cyst) can delay your period for a few days or a few weeks. Acute stress can alos affect your cycle. I would definitely repeat your pregnancy test and if negative, you can relax a bit and wait for your period to start naturally. I typically have not intervened unless 4-6 weeks has passed. An ultrasound may be indicated. If you are perimenopausal, this may be part of the hormonal changes that occur at this time. READ MORE

  • I am having severe itching in my vagina. Could it be a UTI?

    Depending upon your age and sexual activity, severe vaginal itching could be an infection, either yeast or bacterial, an STD, atrophic vaginitis due to estrogen deficiency or a UTI. The burning can occur with UTI'S but they are usually accompanied by other symptoms such as burning on urination, frequency and urgency of urination, etc. A urinalysis with culture will confirm or refute this diagnosis. A visual examination by your GYN would also be helpful if the culture is negative, to rule out other non infectious causes or if you don't improve with treatment. If you are menopausal, vaginal hormone therapy can work wonders. John B Monaco, MD READ MORE
