Chicago OBGYN explains potential causes of abnormal vaginal bleeding

The Chicago, IL OBGYN team at Northwestern Women’s Health Associates S. C. explains the causes of abnormal vaginal bleeding

Abnormal vaginal bleeding can be related to issues with the reproductive system, medical issues, or medications. If you experience abnormal bleeding, you want a team you can trust. With offices in Chicago and Glenview, the OBGYN team at Northwestern Women’s Health Associates offers feminine health care to patients from Chicago to Northwest Indiana and the surrounding areas. During your appointment, our Chicago OBGYN team explains causes of abnormal vaginal bleeding and helps you find a solution for your case.

Normal menstruation occurs every 21 to 35 days. This happens when the uterus lining sheds to start a new reproductive cycle. A normal period may last for a few days or for up to a week. Abnormal vaginal bleeding is defined as any bleeding that is not related to normal menstruation. This may include spotting between periods or even extremely heavy bleeding during periods in which a pad or tampon is soaked in one to two hours. Vaginal bleeding for a woman who has reached menopause is abnormal and should be cause for concern as well.

Possible causes of abnormal vaginal bleeding

If you are experiencing abnormal bleeding, consult your Northwestern OBGYN to discuss potential causes and to determine a treatment plan. Several factors may cause abnormal vaginal bleeding. These may include:

  • Cancer or precancerous conditions – This includes cervical, endometrial, ovarian, or vaginal cancer. Endometrial hyperplasia may cause abnormal bleeding as well.
  • Endocrine system factors – Hyperthyroidism, hypothyroidism, polycystic ovary syndrome, or starting or stopping birth control medication can impact vaginal bleeding.
  • Fertility or reproductive factors – Changes in your reproductive system such as pregnancy, miscarriage, ectopic pregnancy, perimenopause, or vaginal atrophy are causes of abnormal bleeding.
  • Infections – Some STDs, pelvic inflammatory disease, and cervicitis may cause bleeding.
  • Medications – Side effects of birth control, hormone therapy, or intrauterine devices include spotting between periods or abnormal bleeding as your body adjusts to the hormonal change.
  • Noncancerous growths – Cervical or uterine polyps or uterine fibroids can cause bleeding.
  • Trauma or sexual abuse can lead to damage or bleeding.

For patients who experience unexpected bleeding, it is important to consult with your doctor to determine the cause. For some patients, vaginal bleeding may be normal based on age or circumstances. During your appointment, your physician will discuss your medical history and current circumstances to determine the testing necessary to assess your situation.

Certain circumstances may help you determine how quickly to contact your physician.

  • Patients who are pregnant should contact their Chicago OBGYN immediately if they notice vaginal bleeding.
  • Postmenopausal women who do not take hormone therapy and experience vaginal bleeding should contact a doctor.
  • Postmenopausal women who do use cyclic hormone therapy may experience vaginal bleeding that resembles a period. This is known as withdrawal bleeding. Patients who experience more bleeding than the anticipated withdrawal bleeding should consult a physician.
  • Postmenopausal women who take continuous hormone therapy may experience light bleeding for the first six months. Bleeding that lasts longer than six months or that is heavy may be abnormal.
  • Young girls who have not yet shown signs of puberty but are experiencing any vaginal bleeding should see a doctor.

Diagnosing abnormal bleeding

Abnormal vaginal bleeding can be related to issues with the reproductive system, medical issues, or medications.

When you consult with your Northwestern OBGYN, your physician will review your medical history, age, current symptoms, and health. This helps determine the necessary tests to diagnose the exact cause of your symptoms. It is crucial to properly diagnose the cause of your abnormal bleeding to ensure you receive the most appropriate treatment. Diagnostic tools may include:

  • Blood work to check for pregnancy. This also ensures your blood count is not too low if you have been bleeding heavily.
  • An ultrasound may show problems with the ovaries and uterus.
  • An endometrial biopsy removes a tiny piece of the uterine lining for laboratory testing.
  • Sonohystogram is an ultrasound, which fluid is inserted into the uterus
  • A hysteroscopy is performed by inserting a thin, lighted tube through the vagina to examine the cervix and uterus

Once your condition has been diagnosed, your OBGYN team can work with you to determine an appropriate treatment plan. Let your Northwestern GYN know if you experience abnormal vaginal bleeding. Contact our Chicago office today for an appointment with our experienced team. Call 312-440-9400.

    5 Dr. Stanley Friedell, 5 Star Review By Gerilynn H.

    Dr. Regina Belmonte has been providing all the services I have needed for over 12 years. She saw me through both of my pregnancies and her expertise is vast. Even after I moved far away from the city, I still embrace and look forward to her care and services, and I refuse to switch doctors. She is worth the trip! Going through both pregnancies I had to meet with all of the Dr's. and all were wonderful. The nurses are fantastic. I have gotten 98% of what I have ever needed just talking to a nurse. So grateful for this practice and so confident with the care I receive.

    Dr. Abbie Roth is GOLD!
    I have never met a doctor who is caring and brilliant and with a great sense of humor as doctor Abbie Roth. She is very professional and has an excellent bedside manner. When I had a life threatening complication after my C-section, she and her Prentice team of doctors and nurses were such an efficient team under pressure while making sure they explain every process and steps during the situation. Dr. Abbie Roth and her team literally saved my life! I am very fortunate to have met Dr. Roth, I will never forget her and will continue to see her for my future OB/Gyne health. I highly recommend this practice and Dr. Roth!

    If you are new to Chicago or are just looking for a new physician, please make an appointment with Dr. Friedell. This is the first time in my adult life, that a doctor spent an hour with me going over my medical history, asking questions and documenting my history accurately. His assessment and subsequent surgery were all done t a T! I wouldn't hesitate to recommend him or his staff. I have had very positive experiences every time I've gone and I always leave feeling like I've been really seen and heard.

    I was recommended to NWWH through a friend after a year of unsuccessful IUI with my partner. We were seen and cared for by Dr. Friedell. Best decision ever. You will definitely wait for the doctor for maybe 30 minutes past your appointment time but you will not regret it. His thoroughness and patience to explain everything to us in a way we understood was amazing. He was quick to start a game plan for us. We will definitely stick with Dr. Friedell as our OB/GYN.

    Apart from Dr. Friedell, the staff was quick to perform any lab work and ultrasounds with friendly conversation and compassion. This type of service really helps when we've gone through a rough time trying to get pregnant. Definitely make an appointment with Dr. Friedell.

    I have been going to Dr. Friedell for over a year now and he has been nothing less than amazing. When I first came to him to discuss pregnancy, he was incredibly informative and understanding. He was also willing to take the time to answer all of my questions and help in any way he could. He just delivered my son in March and to say he went the extra mile during delivery would be an understatement. I had some complications and with any other doctor I would have had a c-section. Dr. Friedell worked with me and was extremely patient and because of his care and expertise I had a successful vaginal delivery. I cannot recommend him highly enough!

    I have been going to this office for little over a month now due to some complications! I have been seen Dr. Friedell, he is very caring and always made sure he answers all my concerns. I am beyond impressed with my experience with Dr Friedell and his PA " Amber". Dr Friedell called me many times after hours to talk to me about my medical results and answers any concerns that I have.

    I would highly recommend Dr Friedell.

    I have been a patient of this practice for over 5 years now and have only positive reviews of Dr. Feldstein. He was the doctor on call and delivered my third son without any complications. He was knowledgeable, patient focused and went above and beyond to answer my questions and provide a safe and healthy delivery. I also want to note his positive bedside manner to not only my husband and I, but to the nursing staff that was working with him. He was very respectful and I am very thankful to have had him for my delivery. I would recommend this group, Dr. Feldstein in particular without reservation.

    I switched to Dr. Roth mid pregnancy due to health insurance reasons and it was probably the best decision I have ever made in my life. She is definitely warm and funny but also extremely competent and knowledgeable. I would say what makes her stand out from other doctors is how calm and not reactive she is in even the most dire situations. My son was in serious fetal distress (unexpected and not preventable) and she was very calm and reassuring as we literally ran to the OR for my c section. With the rise of c sections today I feel Dr. Roth is one of the few remaining fabulous ob's that truly plans for normal vaginal births (your choice if you want an epi or not) and although I needed a c section I knew it was truly necessary. I could not speak more highly of her, not only did she save my sons life but she made me feel safe, secure and empowered even when decisions and actions were out of my hands.

    I can not tell you how wonderful my experiences have been. Dr. Sharon Wise is my doctor and she is fantastic. She is straightforward and honest about treatments and procedures. I enjoy her sense of humor, and I found her bedside manner when delivering my son to be excellent.
