Life's Medicine FAQ'S

At Life's Medicine we try to help our patients live their best life. Dr. Lopez will do this by taking a practical approach to medicine. Whether managing medical problems, weight issues, thyroid dysfunction or life circumstances we help our patients live a full life.

Life's Medicine is a highly attentive medical practice that focuses on making you better. Whether addressing high blood pressure, diabetes, thyroid issues, fatigue, insomnia, weight or athletic performance issues each patient gets the attention they need and deserve.

Doctors have a desire to help their patients. It has been our experience that insurance makes it difficult to build a well-rounded practice. Life's Medicine is a fee for service practice allowing Dr. Lopez to spend significantly more time with her patients, i.e. being highly attentive. Dr. Lopez will limit the number of patients in order to spend the time the patient needs. This allows time to really listen to patients and take into account what they're feeling, what their lives are like and how they take care of themselves. These factors affect their overall health. Dr. Lopez won't shove them into some pre-determined diagnosis and ignore obvious signs or symptoms, as her goal is to have each patient leave their appointment excited, optimistic and hopeful about their future health.

This is not your conventional medical practice. Dr, Lopez is not contracted with health insurances but can bill insurances for ancillary services (labs). Dr. Lopez is dedicated and committed to helping her patients reach their goals. Dr. Lopez invests in her patients so they can invest in themselves and see ample returns! Living a full and optimal life is good medicine, come get it!


BIO - Dr. Isabel Lopez MD


Vitamin B 12 is one of the most vital nutrients for the body. I would even dare to say that it is the mother of all supplements! Egg yolks, meat, liver, and oily fish are the main dietary sources of vitamin B12.  It is such a special nutrient it requires a certain protein called Intrinsic Factor to carry it from the stomach into the small intestine, where it is absorbed.  No or low Intrinsic Factor effects your bodys ability to absorb this vital nutrient.  So there is a two-part problem here.  Part one is that most of us are not eating a diet with enough egg yolks, meat, liver and oily fish (only because we have been erroneously informed that fat equals high cholesterol, and that is a whole other topic!). Part two is that most of us are not producing enough Intrinsic Factor due to chronic stress, alcohol intake, excess caffeine, sugar, antibiotics, gastritis, medications (antacids, proton pump inhibitors, metformin, etc) or any type of weight loss surgery. So not only are we not eating enough Vitamin B12 rich foods, but we are also absorbing less than we used to because of the way we live!  The result is sub-optimal B12 levels that can lead to sluggishness, mental fatigue, high homocysteine levels, sleeping difficulty, numbness and tingling, depressionI could go on and on because Vitamin B12 is normally involved in the metabolism of EVERY CELL of the human body, especially affecting DNA synthesis and regulation, the production of ATP, fatty acid metabolism and amino acid metabolism. Basically every single inner machination of the human cell requires B12!  It is also a vital component to our bodys methylation process.  Methylation is a key biochemical process that is essential for the proper function of almost all of your bodys systems. It occurs billions of times every second; it helps REPAIR your DNA on a daily basis; it CONTROLS homocysteine (an unhealthy compound that can damage blood vessels); it helps RECYCLE molecules needed for detoxification; and it helps MAINTAIN mood and keep inflammation in check.  Without enough B Vitamins, methylation breaks down, i.e we can't REPAIR, CONTROL, RECYCLE or MAINTAIN.......not good!

The normal lab values for B12 range from 200-1100.  That is a very wide range, but most patients will have symptoms once the level gets below 400, specifically fatigue. So now what? If you have your Vitamin B 12 level checked and you are below 400, I suggest supplementing. If you have a problem with absorbing your B12 due to poor intrinsic factor (which I believe we all have low levels of because of our crazy lives), then increasing your intake of B12 rich foods alone may not make a difference, because you will not absorb it.  By supplementing, I mean adding a daily sublingual (under the tongue) B12 or getting B12 injections, both forms directly absorb B12 into your bloodstream and do not require Intrinsic Factor.

To B or not to B, that is the question.  You can continue to ignore the vague signs and write them off to a busy life, or you can listen to your body and get your levels checked!"

  • Insulin Evil

    Ever look at yourself in the mirror and think "what in the #@$% happened to me?" In high school you were thin, in college fit and active, and now you look like one of your relatives. You snore (no thanks to that extra chin pushing on your trachea), you are tired, your clothes are getting tighter (you officially have love handles) and it is getting harder to tie your shoes without coming up for air. What happened to thin you, the one that could eat whatever they wanted, run a few miles and drop the weight? Believe it or not that person is still buried somewhere in there, you just have to make some adjustments that will facilitate their rebirth. In order to do that you first have to understand how you got to where you are now.

  • It could be your thyroid!

    How many of you have been to your doctor absolutely convinced that you are having symptoms consistent with an underactive thyroid (thanks to your extensive internet research)? You have fatigue, weight issues, difficulty concentrating, memory problems, hair thinning, dry skin and an indifference to life among other symptoms. How could it not be your thyroid? You get your blood checked and your doctor tells you "it's not your thyroid the number is within normal range". You leave there feeling completely hopeless. "I must just be getting old", you tell yourself. Well guess what? It could definitely be your thyroid!! What most primary care doctors do not realize is that the American Association of Clinical Endocrinologists (AACE) has narrowed the parameters of the normal range and now patients who results looked normal before now are considered HYPOTHYROID! Woo hoo!!!!! Lemme splain……

  • Understanding Insulin Resistance

    We heard a lot about insulin in the days of low-carb diets. And for good reason. Problems with insulin are a root cause of some of the most dangerous health conditions, as insulin affects almost every cell in the body.

    Insulin plays a critical role in how your body uses food. Its most important role is to lower the concentration of glucose in your blood. When you eat, your digestive system breaks food down into glucose, and the glucose recirculates in your blood stream. In response to the rise in glucose after a meal, the pancreas releases surges of insulin, whose job is to clean the glucose from the blood.

  • Stressed out? Sleeping poorly? Eating your feelings?

    In today's economic climate most of us have felt the pinch of our country's current financial embarrassment (with the exception of those privileged few that caused this disaster and where fortunate enough to be bailed out!). Any situation that makes you feel uncomfortable causes stress in your body. Emotional, physical and mental uneasiness are triggers. Stress can be a ticking bomb that wreaks havoc on your body if not dismantled properly. Everybody handles stress a little differently. Some of us drink fermented liquids, some of us eat, some of us lose sleep. When stress is not managed properly (and surprisingly, eating and drinking your feelings is not a good option) your body is at risk for certain maladies. My father used to say "Mija, in life you gonna have estress….. that's life". He is right, we will always have stress, it 's how you handle it that can make all the difference. Lemme splain…..

  • Fat-Free vs. Sugar-free

    Which is better? Working at a weight loss clinic I get that question a lot. So I thought I would spend a little time explaining the difference. I personally am on Team Sugar Free. Some may argue that it is better to be on Team Low Fat. I actually was on that team myself until I began to research and truly understand the difference between the two and how it affects the body. Now I am sugar free all the way. Lemme splain……….
