Hypothyroidism can quietly disrupt your energy, metabolism, mood, and cognitive clarity, but with the right evaluation and structured care, true thyroid balance is possible.
When Your Thyroid Slows Down, Your Whole Body Feels It
Hypothyroidism is one of the most commonly overlooked drivers of fatigue, weight gain, hair thinning, brain fog, depression, and cold sensitivity. Many patients are told their labs are “normal” while their symptoms persist. At Health & Vitality Center, Dr. Shiva Lalezar takes a root-cause approach to hypothyroidism treatment in Los Angeles, evaluating thyroid function in the context of inflammation, metabolism, gut health, detox pathways, and hormone balance. Schedule your consultation with Health & Vitality Center to explore a more comprehensive approach to hypothyroidism treatment.
What Is Hypothyroidism?
Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones to meet the body’s needs. These hormones regulate metabolism, temperature, heart rate, digestion, mood, and energy production. When thyroid function slows, the entire system slows with it. Common symptoms may include:
Weight gain or difficulty losing weight
Persistent fatigue
Cold intolerance
Hair thinning or hair loss
Dry skin
Constipation
Brain fog and slowed thinking
Depression or low mood
Irregular menstrual cycles
In some cases, symptoms are subtle. In others, they significantly affect daily performance and quality of life.
Why Standard Treatment Sometimes Falls Short
Conventional care often focuses solely on TSH levels and prescribes medication when values cross a defined threshold. While this approach works for some patients, others continue to struggle even after beginning medication.
Effective treatment of hypothyroidism in Los Angeles requires looking beyond a single lab value and understanding how the thyroid interacts with the rest of the body.
Reasons may include:
Incomplete thyroid testing
Poor conversion of T4 to active T3
Inflammation interfering with thyroid receptor sensitivity
Heavy metal burden affecting hormone signaling
Gut dysfunction impairing absorption

A Root-Cause Approach To Hypothyroidism Treatment In Los Angeles
At Health & Vitality Center, Dr. Shiva Lalezar evaluates thyroid health within the larger functional medicine framework. Rather than isolating the thyroid gland, she assesses the systems that influence hormone production, conversion, and cellular response. This may include:
Comprehensive thyroid panel evaluation
Assessment of inflammation and metabolic markers
Review of adrenal function
Evaluation of gut health and nutrient absorption
Screening for heavy metal burden when appropriate
This structured evaluation helps determine whether thyroid hormone therapy in Los Angeles is needed alone or alongside deeper metabolic and detox support.
Thyroid Hormone Therapy In Los Angeles
For patients who require medication, thyroid hormone therapy in Los Angeles is carefully individualized. Not all patients respond the same way to standard T4-only prescriptions. Some patients benefit from:
Nutrient optimization to enhance receptor sensitivity
Adjusted dosing strategies
Combination T4/T3 therapy
Support for improved hormone conversion
The goal is not just to normalize lab numbers, but to restore energy, cognitive clarity, metabolism, and long-term stability.
Thyroid Hormone Replacement Therapy In Los Angeles
When thyroid production is significantly impaired, thyroid hormone replacement therapy in Los Angeles may be necessary. This therapy replaces deficient hormone levels so the body can resume proper metabolic regulation. However, replacement therapy is most effective when:
Gut health is optimized for proper absorption
Inflammation is addressed
Detox pathways are supported
Adrenal balance is stabilized
At Health & Vitality Center, thyroid hormone replacement therapy in Los Angeles is integrated into a broader treatment strategy rather than used in isolation.
The Role Of Heavy Metals And Detoxification
Heavy metals such as mercury and lead can interfere with thyroid hormone conversion and receptor sensitivity. When conversion is impaired, patients may experience symptoms of hypothyroidism even if lab values appear borderline.
Dr. Shiva Lalezar is one of the few physicians in Los Angeles offering IV chelation therapy as a core pillar of care when appropriate. In certain cases, supporting detox pathways can enhance thyroid responsiveness and improve symptom stability. Detoxification is not applied universally. It is considered based on clinical history, symptoms, and testing.
Gut Health And Thyroid Function
The gut plays a critical role in hormone metabolism and nutrient absorption. When the gut is inflamed, the thyroid often struggles.
Conditions such as dysbiosis, leaky gut, or chronic inflammation can impair thyroid hormone activation and reduce medication effectiveness.
Supporting gut repair may help:
Improve absorption of thyroid medication
Reduce autoimmune activation in Hashimoto’s thyroiditis
Lower systemic inflammation
Stabilize immune regulation
Testimonials
“I highly recommend Dr Lalezar.”
I went to Dr Lalezar frustrated that after having seen 4 specialists, 3 years of aggravation, having gained more than 30 lbs, no one could figure out what was wrong with my thyroid.
Well she did in the first 10 min I met her. I also found out that the level of mercury in my body was thru the roof. She fixed that too with her chelation treatment and only in a few sessions.
Not only she is the most pleasant doctor you will meet, but also she is one of the brightest. She thinks in 3 dimensions and combines her knowledge of western medicine with osteopathy beautifully. She is extremely competent.
Her office staff are so kind, considerate, and patient orientated. Dr. Lalezar has spent so much energy, turning her office and treatment center into a beautiful, calm, zen spot, following Feng shui elements. You will never feel like you are in a doctor’s office.
I have come across people who have come to her office as far as Barstow. I highly recommend Dr Lalezar.

“I feel better than I have felt in years”
“I feel better than I have felt in years thanks to Dr. Lalezar. Seriously, I had been to other doctors and when they asked how I felt and I said “meh” they just shrugged it off. It turns out I was suffering from extreme mercury toxicity.Thank goodness Dr. Lalezar knew what tests to give me. She also has prescribed hormones and various minerals and micronutrients to get me feeling better than ever. Those, along with IV chelations have made incredible transformations in my health.
Three friends in the past week have told me how good I look. I also brought my 16-year-old daughter to see her for a full exam and Dr. Lalezar has been compassionate, thoughtful, and nurturing to us both.”

“Dr. Lalezar cured me and GAVE ME MY LIFE BACK.”
Starting in February 2018 I started to develop a mysterious, severe face rash that conventional doctors could not determine the cause. By March, it progressed and it was very painful…it felt like my face was on fire and weeping blisters developed on my face. It was horrible. I didn’t want to go anywhere. Doctors tried me on all sorts of medications. I also switched out all my makeup and skin care products. Nothing cured it. Additionally, the doctors would prescribe Prednisone, which helped, but as soon as I tapered off, the painful rash would reappear…and worse each time! The conventional doctor finally told me he thought I was developing psoriasis. I refused to believe that. I intuitively knew I was reacting to something.
I spent countless hours researching possible causes on the Internet. I thought maybe I developed an allergy to a certain food. So I went on an elimination diet and for several weeks only ate fruits, vegetables and salmon. I also got allergy tested for cat dander and goose feathers as I theorized maybe I developed an allergy to my cats or to my feather comforter. None of this helped. The burning rash and blisters continued to return.
I didn’t want to return to the conventional doctors. They were at a loss, too. I knew I had to take a different approach.
I found Dr. Lalezar’s website and resonated with what I saw. I had treated with functional medicine practitioners with great success in the past.
Dr. Lalezar cured me and GAVE ME MY LIFE BACK.
How?
Ten years ago I was diagnosed with a nickel allergy. During my Internet research, I studied nickel allergy and saw that many magnets contain nickel. In July 2017 I started wearing magnetic lashes. I thought it was pretty far-fetched that my lashes – with extremely tiny magnets – would be the cause of my face rash. Because my rash didn’t start developing until many months after I started wearing the lashes. And, even though the rash did start underneath my eyes, the rash had spread to many parts of my face, including by my ears, my forehead and underneath my chin.
Keep in mind, even when my face was at its worst, I CONTINUED TO WEAR THE LASHES. I figured because I couldn’t wear makeup, those lashes were the one element of beauty I could easily still wear.
Dr. Lalezar took ample time to meet with me and listen to my medical history. I mentioned my nickel allergy and told her about the magnetic lashes. (Although, again, I still thought it likely wasn’t the cause.)
She submitted my blood for testing and she also had me to a six-hour urine test that would test the presence of many heavy metals in my body.
In the meantime as I was awaiting results of my labs, I contacted the company where I bought the lashes from. They couldn’t help me when I called them, so I emailed the company. Nine days later they responded to me, informing me that the magnets on their lashes were indeed “black nickel coated.”
I decided to stop wearing the lashes to see what would happen. The last day I wore them was April 25, and I was in the middle of tapering off a round of Prednisone. (If the lashes were the culprit, then my nickel reaction would occur three days later per my allergy results regarding nickel 10 years ago.) My Prednisone taper ended April 26.
The rash returned; however, by April 28, the rash would have progressed to the oozing stage. It didn’t. The red, dry, itchy rash appeared in various parts all over my face, but it didn’t burn as bad and it never started oozing. It plateaued. Why didn’t it progress this time? The only thing I changed was I stopped wearing the lashes. Now I was pretty convinced the lashes were the culprit.
On April 30, I saw Dr. Lalezar because the results came in on my heavy metals testing. It revealed that I had an excessive amount of nickel in my body…more than four times the limit a human being should have in the body. It was evident that the nickel-plated magnetic lashes was the primary contributor to my face rash.
After months of obsessive research and dealing with the terrible rash, and with the help and expertise of Dr. Lalezar, I was overjoyed and eternally grateful to have finally found the cause of my ugly and painful face. Needless to say, I immediately threw the lashes away, and Dr. Lalezar started me on IV chelation therapy to expel the nickel out of my body.
A couple of weeks later (by Mother’s Day!), my face was almost fully healed. I will forever be grateful to Dr. Lalezar for helping me solve the terrible mystery of my awful face rash that was ruining my life. Since this experience, I’ve done further research on heavy metal toxicity, and it’s amazing the kinds of health problems people can suffer from due to large amounts of heavy metals in their bodies. It is a contributor to many types of ailments and illnesses. And mainstream medical providers do not address this.
Thank you from the bottom of my heart, Dr. Lalezar and team!!!

“Dr. Lalezar is wonderful at examining the whole picture”
“I am currently seeing Dr. Lalezar to get to the bottom of several issues including fatigue, hormone imbalance, high cholesterol, and mood disorder. I am trying to get off some of my medications. I am so tired of traditional doctors just giving you a pill for your symptoms.
Dr. Lalezar is wonderful at examining the whole picture: hormones, nutrition, toxicity, and the environment. I really feel that she is interested in helping me. Just for example, I changed my diet and started taking Red Yeast Rice per her advice, and my cholesterol went down 40 points in 3 months! The bio-identical hormones have also made a huge difference in my energy levels.
Functional medicine requires more involvement and responsibility from the patient too. If you want to take control of your health, I recommend Dr. Lalezar and her capable staff.”
– L. L.
“She was very professional and kind”
I went to see Dr. Lalezar for answers regarding my overall health and low immune system. After taking lots of blood samples and a urine sample and waiting for a few weeks Dr. Lalezaradeh’s office called me in to meet with the Dr who went over ALL of my test results and figured out why my immune system is down and drafted a plan to get me back on track (which worked). She was very professional and kind and her vitamin C injection is like medical crack it will have you up and running in no time. It really works! The only down fall is that she tests for EVERYTHING and somethings are NOTcovered through insurance so make sure you have met your deductible. Oh and shout out to the staff who are very warm and welcoming.
– Keith M.
“Great experience.”
Great experience. And I will continue come to Dr. Lalezar Office for my IV vitamins and minerals. Today I start a program to see if my body has a heavy metals and if I do Dr. Shiva Lalezar will help me to clean my body from it. Let’s start my journey.

What Patients Can Expect
Patients seeking hypothyroidism treatment in Los Angeles often pursue improvements such as:
Increased daily energy
Improved mental clarity
Healthier hair and skin
More stable mood
Easier weight regulation
Improved digestion
Better temperature tolerance
While every case is unique, the goal is to create sustainable improvement by addressing both hormone levels and the systems that influence them.
Hypothyroidism vs. Hyperthyroidism
While hypothyroidism reflects reduced thyroid hormone production, hyperthyroidism involves excessive hormone output, which can accelerate metabolic function. Symptoms may include rapid heart rate, heat intolerance, anxiety, unexplained weight loss, and sleep disruption.
Because thyroid-related symptoms can overlap with adrenal, metabolic, and inflammatory conditions, accurate diagnosis requires comprehensive evaluation. At Health & Vitality Center, thyroid testing is interpreted within a broader functional framework to determine whether symptoms are driven by hypothyroidism, hyperthyroidism, autoimmune thyroid disease, or related systemic imbalances.
Why Choose Health & Vitality Center?
Health & Vitality Center has served Los Angeles since 2009 and is led by Dr. Shiva Lalezar, a functional medicine physician known for identifying the root causes behind complex endocrine conditions. Rather than relying solely on medication, the practice uses a structured, sequential approach that addresses metabolism, gut health, detoxification, and hormone balance together. Dr. Lalezar also offers advanced detox strategies, including IV chelation therapy when appropriate, making her approach to hypothyroidism treatment in Los Angeles both comprehensive and precise. Contact Health & Vitality Center today to begin a more complete and individualized approach to thyroid care.
What is the difference between thyroid hormone therapy and thyroid hormone replacement therapy?
Thyroid hormone therapy refers broadly to medication used to support thyroid levels. Thyroid hormone replacement therapy specifically replaces hormones when the thyroid cannot produce enough on its own.
Why do I still feel tired even though I’m taking thyroid medication?
Fatigue may persist if inflammation, poor T4-to-T3 conversion, adrenal imbalance, gut dysfunction, or toxic burden are interfering with how your body uses thyroid hormone.
Can hypothyroidism cause weight gain?
Yes. A slowed metabolism due to low thyroid hormone can contribute to weight gain or difficulty losing weight, especially when combined with insulin resistance or inflammation.
Do you treat Hashimoto’s thyroiditis?
Yes. Hashimoto’s is an autoimmune form of hypothyroidism. Treatment focuses on stabilizing immune function, reducing inflammation, supporting gut health, and optimizing thyroid hormone levels.
How long does it take to see improvement with treatment?
Some patients notice changes within weeks of optimized therapy, while others require several months as metabolism, inflammation, and hormone balance stabilize.
