Common Conditions We Treat

Poly Cystic Ovarian Syndrome is not a reproductive disorder. It is a whole-body endocrine disorder that impacts your hormones. PCOS symptom flare-ups have a root cause trigger, whether chronic inflammation, poor gut health, or insulin resistance - and many women have all three of these triggers combined. This is what causes your common PCOS symptoms: weight gain, hair loss, infertility, period issues, excess body hair, and more. 

The good news is that these symptoms can be subdued and even eliminated completely with a natural, non-invasive, and functional approach. This includes in-depth advanced testing, change in lifestyle and diet, and supplementation when needed. You can learn more about our treatment process for PCOS on this page.

Perimenopause and Menopause Symptoms

Menopause is a common, unavoidable experience for midlife women. However, the symptoms it causes can seriously interfere with our lives. Many women who are going through menopause or perimenopause (the transitional period before you officially enter menopause) experience things like disturbed sleep, hot flashes, anxiety, low libido, hair loss, and more. We often think that because these are common occurrences, we simply have to suffer through them. But this is not the case. 

At Precision Health MD, we’re experts on women’s health at all ages. For perimenopausal and menopausal women, we utilize Bioidentical Hormone Replacement Therapy. Learn more about hormone replacement therapy for women in menopause here.

Digestive Issues

SIBO, IBS, and Digestive Issues

Small Intestine Bacterial Overgrowth (SIBO), Irritable Bowel Syndrome (IBS), and other digestive issues can be a nightmare. These conditions can greatly affect your health, causing you not to be able to absorb nutrients properly, frequent stomach aches and issues, diarrhea and constipation, indigestion, and more. 

Common digestive issues are caused by problems in the gut - whether that’s your intestinal lining, too much or too little bacteria, medication, outside stress, and so on. Changing your diet is one of the best and most obvious ways to improve gut health. It’s important to see what foods work with your body and fuel it with what it needs. Our advanced approach with an in-house nutritionist and a board-certified doctor will help you determine a plan to get your gut health back on track. 

Hormone Imbalances

An imbalance of hormones can cause so many problems for women, like Pre-Menstrual Syndrome (PMS), Pre-Menstrual Dysphoric Disorder (PMDD), acne, Poly Cystic Ovarian Syndrome (PCOS), infertility, weight gain, and so much more. With the standard medical approach, women are prescribed birth control to help their symptoms. 

The pill only masks symptoms and that’s the problem with this approach.  However, this doesn’t address or treat the root cause. 

At Precision Health MD, we know through science-based studies and research that we’re able to balance hormones with a natural, non-invasive approach that can work in tandem with your medical care.

Thyroid Issues

Thyroid Issues

Thyroid disease, Hashimoto’s, and other issues can go undetected for a long time. And yet, they can be the root cause of all your symptoms. If you’ve been to the doctor, gotten labs, and everything with your thyroid still looks fine, you may need additional testing to see what’s going on and if thyroid issues are at the root of your problems. 

We work with you to devise a plan to restore your thyroid. Our integrative approach is natural and noninvasive and can complement medications or protocols your doctor prescribes. Call 714-272-3477 to schedule an appointment.
