    [Review #721] 2023-007…read more I haven't been maintaining/checking my health since COVID-19 lockdown 3 years ago so I'm wayyy past due for a physical or routine check-up. One of my required exams is a retinal photo as part of the annual diabetes eye screening to examine eyes for signs of diabetic eye disease, including diabetic retinopathy, as well as other eye problems, such as glaucoma & cataracts. It was almost a month ago from the initial screening & left my PCP's office will a very long "after visit summary." Out of habit, I filed it away before my calendar alert pinged me that my follow-up appointment was coming up & I didn't complete any of the listed exams. \(`0´)/ Luckily, the retinal photo takes 10 - 15 minutes & appointments are easier to come by. Good thing was a South Bay location so I didn't have to trek up to Santa Monica, Century City, or Westwood (gulp!); I can't imagine driving that distance for this quick exam. I called UCLA Health South Bay Endocrinology & was able to get an appointment before my PCP follow-up. I initially wanted it on the hour but the receptionist said to check-in 15 minutes early, & I didn't think I could make it on time so took a 2:20 PM slot. I arrived just after 1:45 PM & could have made the earlier time; I ended up sitting in the reception area for 30+ minutes when there was no one ahead of me. (ノ__ヽ) I did get called right on the dot. The technician (think his name was Cuong?) was friendly & patient, explaining the process & what I'm suppose to do. He also assured me that the equipment was cleaned so I can confidently place my eye on the bulbous part of the scanner. It took me awhile to position myself/right eye to see the "green" light, then standing still to maintain the green light. It was faster with my left eye because I knew what I was doing. Whew! LOL Not counting the lobby wait time, I was done in under 10-mins. What is endocrinology? It's the study of hormones, which are essential for our everyday life, controlling our mood, stress, growth, temperature, sleep, etc. The doctor - endocrinologists - diagnose & treat conditions like diabetes, thyroid diseases, infertility, growth issues, metabolic disorders, osteoporosis, some cancers, & disorders in the hormone-producing adrenal glands & pituitary glands. I needed to look up endocrinology because the other facilities were aptly named diabetes or health center; I wanted to make sure I was in the right place. Other than the check-in "waiting period," it was a fast & smooth process. UCLA Health South Bay Endocrinology is located in Madison Park Medical on the 1st floor. The medical center has 2 entrances; one off PCH, which is strange since there's no street parking, & the other is on the back, entering from the parking lot. There's plenty of parking spaces on the east & west sides, with the north end mostly filled since it's closest to the entrance. The facility was open, bright, & clean. The reception area's flatscreens showed serene images but it got my 7 YO son worked up, asking a laundry list of questions about the displays. Why are there aquatic life in the flowing stream? Is that mountain that you can climb? Why don't they put on a show to entertain me? Yeesh! ;-) Still, I recommend UCLA Health South Bay Endocrinology for all your hormonal needs.

    I recently visited Dr. Navabi for help managing my Hashimoto's/Hypothyroidism after a long journey…read moreof self-advocacy, research, and appointments with multiple doctors. I went in prepared with a clear idea of the care and testing I believed would help. Unfortunately, my experience was disappointing. From the start, many of my requests were dismissed, and I was told I didn't understand my own condition. When I mentioned my struggles with weight loss despite being in a calorie deficit, he responded with frustration, saying I should only eat one meal a day if I wanted to lose weight. This felt dismissive and insensitive, especially given the complex nature of hormonal issues. An assistant was in the room taking notes, and her discomfort was noticeable; she wouldn't even make eye contact with me. It seemed she, too, recognized how extreme some of his advice sounded. When I asked for lab work to explore further, he refused some of the tests, stating they weren't necessary. Overall, I felt unheard and unsupported, which is the opposite of what I was looking for in a specialist. I would like to add that if this was just a review of the office and its staff (outside of my experience with this Dr), my review would be 5 stars.
