What Patients Say
Great office, best doctors. Dr Kalva is amazing to work with. Appreciate everyone here in the office, so helpful and kind.
Absolutely fabulous place. Best doctors ever.

I have been seeing Dr. Kannankeril for a few years and she is actively helping to get my body balanced and healthy. She listens, is knowledgeable, up to date with new treatments and excellent in her field. I always feel confident in her care that she is supporting me to great health in a personal way.
Dr. Kalva is an EXTRAORDINARY GEM of a doctor. HE IS ONE OF A KIND. He’s compassionate, warm, and highly skilled in functional medicine. He has great knowledge on thyroid issues and progressive treatment. He’s a wonderful communicator with teens and parents. We have been so blessed to find him. His care has been transformative for our family.
Dr. Coy Roskosky is the best Chiropractor I’ve ever been to! I even trusted him working on my children. My son played football and Dr. Coy help tremendously!
This is an excellent dentist office. After moving to the area, I struggled to find a great dentist. Most dentists in the area were still okay with mercury based fillings and routinely told me I had cavities when I suspected that was not true. NIHA provided a healthy experience and in my opinion are much more trustworthy.

BPH Keeping You Up at Night? Natural Treatments That Help
Benign Prostatic Hyperplasia or BPH is one of the most common ailments faced by men as they age. In fact, 50% of all men between 50-60 years of age, 75% of men in their seventh decade of life, and 90% of men over 80 will be affected to some extent by changes in their prostate. While not a malignant progress (not cancer), BPH is characterized by increased growth of the prostate gland due to proliferation of the cells of this organ. As the prostate enlarges it compresses the urethra impeding the flow of urine out of the bladder during urination. This leads to the common lower urinary tract symptoms (LUTS) that bring men with BPH to the doctor.

Do the Holidays Make You Sick?
Yes, for most people they do. If they don’t get you with all of the sugary desserts, exposure to the germs of your friends and family, and the cold weather, they’ll get you with the stress of planning and traveling! Not to mention the financial stress many people face at this time of year. While the promise of a new year offers some people hope and inspiration, it offers some an excuse to drink too much, a reason to feel lonely and a pass for gluttony. No, the Grinch is not writing this article – but I offer some advice on how to make this year’s festivities come without consequence.
