Can You Blame Your Thyroid for Your Weight Gain? Santa Monica, CA
Doctor Diagnosis Santa Monica, CA

Nestled in the middle of your lower neck is a small, butterfly-shaped gland that impacts nearly every cell in your body. Among many other important body functions, your thyroid plays a strong role in regulating your heart rate, your body temperature and your metabolism. Unfortunately, this also means that your thyroid helps control your weight. This leads many adults (especially women) wondering whether they can blame their thyroid for that climbing number on the bathroom scale.

While we know that thyroid disease is not the only cause of weight gain, it is a common medical condition that can certainly influence your weight if it is not managed and treated. According to the American Association of Clinical Endocrinologists, approximately 27 million people in America suffer from thyroid disease and 13 million people are currently undiagnosed. Your risk of developing thyroid disease becomes greater with age, and women are seven times more likely than men to be diagnosed.

How Thyroid Hormones Impact Metabolism

The thyroid gland releases hormones into your bloodstream that help regulate your metabolism. When the thyroid is not producing enough hormones, it is called hypothyroidism. This is the type of thyroid disease that is commonly associated with slow metabolism and weight gain.

Thyroid hormones impact fat metabolism and carbohydrate metabolism. In terms of fat metabolism, the thyroid helps your body burn fat for energy and raises your basal metabolic rate (BMR). If the thyroid isn’t doing its job, your BMR will be lower, which means you won’t be burning off as much fat as you should even when your body is at rest. When it comes to carbohydrate metabolism, your body needs thyroid hormones to stimulate the production of glucose so that it can break down carbs and use them for energy. Your brain also needs glucose for function and energy. Without sufficient thyroid hormones, your overall metabolism can’t work at full speed, which means your body can’t fully use food for energy and weight gain result.

Other Symptoms of Hypothyroid

How do you know if your weight gain is due to low thyroid? There is a blood test that can confirm or deny optimal thyroid function. However, hypothyroid often produces several other notable symptoms besides weight gain, including the following:

  • Extreme fatigue
  • Depression
  • Forgetfulness
  • Slow heart rate
  • Dry, itchy skin
  • Thinning hair
  • Voice deepening
  • Intolerance to cold
  • Irregular menstrual cycles
  • Infertility
  • Constipation

Dr. Michael is the most Caring Dr. I have had the privilege of having taking care of my health needs. His calm and personal demeanor is above and beyond what I have ever experienced. I have never had issues with the the waiting time but, if ever I did I would not complain because he is worth the wait. I get his complete attention the entire visit. When I leave I feel very confident that he has completely covered my heath needs from head to toe. I would recommend him to anyone who wants is concerned or wants a Dr. to be concerned about their health.

Dr. Michael has been our family doctor for over 10 years. He has always been the main pillar in our family care; specially a few years ago when my father wouldn’t have been able to get through a very difficult period without his care. He always goes the extra mile. His staff is amazing. Anita, his nurse, always efficient, loving and caring. Aileen, in the front desk, always responsive and helpful. I’m very grateful to have them on our side.

I could literally write pages about Dr. Michael. I thankfully met him and his staff over 13 years ago after I had been suffering from a serious lung infection for over a month that 2 other doctors had missed.- 1 due to being totally arrogant and thinking I just had a cold. I was burning up and so sick I could barely walk. Dr. Michael took the time and actually listened to me - instead of just saying its probably just the flu (as the other doctors had done) or just a cold and sending me home, he actually did a complete physical on me an then had the intuition to order a chest x ray on me (I was not even coughing at the time) and then really looked at it and discovered that I actually had a really serious lung infection and started me on antibiotics. While this may sound like no big deal - it actually was, as he actually saw that it was not a normal looking lung infection and I later learned he went above and beyond and had a infectious disease specialist look at the x ray just to be safe and as he suspected it was even more serious. Since that day he has always been my main doctor. I would also like to add that I have a serious long term health condition and most doctors would generally attribute many of my current and past health issues to my main condition (it usually is the case) but Dr. Michael always looks at whatever is happening to me at the moment as if I was a new patient. This is probably his biggest talent and gift as a doctor as he has on more than one occasion over the years thought outside the box with me and has figured out quickly why I was sick at the time - sometimes it was minor but more than a few times it was really serious. His quick way of thinking and knowledge and intuition is what kept me from getting sicker and going into the hospital. If you are looking for a doctor that actually treats you like a person and not a number then see this man. I am not a celebrity or a wealthy person - far from it - but he treats me like I am - many Vets like myself go to the VA and its a great blessing but I just do not have the energy to go there as its so big. Dr. Michael is seriously brilliant and really patient and I am truly thankful I found him.

Dr. Michael takes the time to explain the meaning of medical terms and test results in a way that a lay person can understand. He is very thorough and answers any question that you may have. His staff is also very professional and competent at their tasks. Given a choice, I wouldn't go anywhere else.

Tim Whalen

Dr. Michael is an intelligent caring human being who is focused on positive outcomes. He has a great ability to synthesize the details of lab results and other tests into preventive measures. I greatly respect his approach to care.

William Barry

A very smart and caring doctor. Very intuitive and yet he will base his decisions on test data. Patient for over 10 years. 5 stars
