Parathyroid Scan

July 09, 2018 11:48 am

A Parathyroid scan or Sestamibi scan may be needed if the typical weight loss surgical reasons for elevated PTH levels have been addressed. Sestamibi is a small protein which is labeled with the radio-pharmaceutical technetium-99. This very mild and safe radioactive agent is injected into the veins of a patient with overactive parathyroid and is absorbed by the overactive parathyroid gland. If the parathyroid is normal it will not absorb the agent. The scan below shows the uptake of the agent.

Calcium, Vitamin D and Parathyroid hormone are routinely measured on yearly follow up for most post weight loss surgical (WLS) patients. Elevated parathyroid hormone (PTH) may be caused by Vitamin D deficiency or calcium deficiency (most common in post WLS) or by over active parathyroid gland(s). In the latter case, if one of the four glands is overactive then this is knows as a parathyroid Adenoma. If all 4 are over active and are secreting too much PTH, this is known as hyperplasia. Ultrasound of the neck, may identify an enraged parathyroid gland (adenoma) which is located behind the thyroid gland. Given the large area where the parathyroid gland may be located, additional tests are needed to not only identify the location of the gland(s) but also to distinguish between single gland (adenoma) or multiple glands (hyperplasia) cause for the elevated PTH. It is important to investigate all avenues and testing in parathyroid hormone elevation and in some cases, not to rely on one test for your diagnosis. It is also imperative that weight loss surgical patients take their supplements routinely and consistently and have their laboratory studies followed at least yearly.

Back on Track 2017 Giveaway

Let’s get back on track 2017 after the holiday season! The holidays were wonderful but if you find yourself with a few extra souvenirs don’t feel alone. The average American gains between 1-8 pounds during the holiday season and I am no exception. Let’s get back on track 2017 together.

Time to clear out the kitchen! Disposing of temptations and high trigger foods is the first step to getting back on track. If the food isn’t easily acquired then it is less likely to be consumed.

Stock up on high protein and whole, unprocessed foods that are low carbohydrate and nutrient dense. When quality foods are easily available we are more likely to stay on track with the types of foods we should be eating. Simple sugars/carbohydrates are the biggest culprit of holiday weight gain. We need to go back to the basics of hydration, high protein, low carbohydrate/sugar, vitamin/mineral supplements and exercise. Simple sugars and carbohydrates are easy for our bodies to use and absorb and cutting them back can jump start your weight loss. Each individual needs to identify the daily carbohydrate intake that works for them. Some people stay under 50 grams of carbohydrates daily. You may also need to look at your protein and fat intake. All excess nutrients absorbed have the potential to turn into fat mass and inhibit weight loss. Metabolism video.

Hydration is an important ways to start getting back on track. Water is essential to life functions. The brain is 85% water, blood is 80% and muscle is about 70% water. Hydration aids in digestion, eliminating waste, byproducts and toxins. It also can decrease the feeling of hunger. Lack of hydration can increase fatigue which can lead to craving high carbohydrate foods to increase energy.

Protein’s importance in almost every bodily function and muscle mass can not be ignored. High quality complete Protein sustains muscle mass during weight loss, aids immunity, antioxidant function, and enhances leptin and insulin function. Filling up on protein first will help with carbohydrate carvings and give a sustained satisfied feeling. A prior blog post gives additional information on the importance of protein and the effects of protein malnutrition. WLS makes daily protein intake important but especially after Duodenal Switch, protein is a necessity of daily life.

Vitamins, minerals and supplements will ensure the body has the nutrients it needs to function adequately and can keep cravings at bay. Deficiencies in vitamins and minerals can cause cravings for foods. Vitamin and minerals are essential to muscle function, red blood cell production, bone health, and numerous other physiologic functions. We may all slack off on our supplements occasionally but now is the time to get back into the habit of daily vitamins and mineral supplements. A daily vitamin, mineral, and supplement routine is a lifetime commitment after Duodenal Switch or any WLS. Here is a list of commonly used supplements.

Exercise can increase weight loss, overall well being, mental well being, mood, alertness, improve digestion, improve sleep, and increases energy levels. Exercise does not have to be a daunting task. Simply adding 15-30 minutes of activity can give added benefits. Yoga, walking, dancing, lifting weights, hiking, and sports activities can be included or added to more traditional forms of exercise. There are many free online videos for all types of exercise available.

Finding a new hobby can keep both your hands and mind busy, curbing the unconscious eating of foods that are high in sugar and carbohydrates. Adult coloring books, drawing, painting, knitting, crocheting, sewing, dance lessons, gardening, learning to play an instrument and many others are great ways to use your time and expand your quality of life and brain function. New hobbies can also help establish new coping skills.  Our previous post on Coping Skills After Bariatric Surgery can be found here.  There are a whole host of online videos for “how to” on new hobbies.

Teaming up with others can also help increase weight loss and compliance. Support from friends, family and other groups will assist you. There is a whole gamut of support group online and in person. If you have fallen out of the habit of attending our support group or webinars get back to them. You can find our schedule and announcements regarding webinars here. Our Central Valley Bariatric Facebook page also gives daily inspirational messages, protein recipes and articles and any new information or research available. There is also our Duodenal Switch Facebook Group. Anything that increases accountability is a benefit and motivates us to stay on track.

Experiment with new recipes and flavors that are bariatric friendly and within your dietary needs.  There are so many options for quick and easy meals.  We have several recipes on our page for all stages following weight loss surgery and Duodenal Switch. However, there are endless option on the internet in Paleo, low carb, and high protein type recipes.

In the spirit of new starts and getting back on track 2017, we are having a giveaway with the basics to get back into the swing of things. This year we are looking for before and after weight loss surgical journeys.  Share your weight loss journey! Don’t be shy, your journey can inspire others and/or motivate yourself. To enter the Back on Track 2017 Giveaway, please submit your weight loss surgical journey with before and after pictures to contact@dssurgery.com or you can also post your before and after pictures on our Facebook page. You will also need to sign a release for the use of your story on our website. We will draw 2 names from those that enter by announcing it on our FaceBook page or by e-mail on January 31, 2017. You must submit your mailing information to contact@dssurgery.com in order to claim the prize.

Duodenal Switch and Fat in The Diet

May 21, 2015 12:35 pm

When I perform the duodenal switch operation,  the common channel is a percentage of the total small bowel length and  I also account for the  patient’s metabolic rate. Two individuals with a BMI of 50, should not have the same common channel. If  we compare two patients, one of them is a 20 years old male who is 6’2″ and the second patient is a 60 year old female who is 5’4″, we can see how this applies. These two patients have very different metabolic needs and requirements. When the Duodenal Switch is performed in this fashion, the common channel based on a percentage of total small bowel length and metabolic needs, the patients post op diet works best when it is a well balanced, protein based diet. The basic principals are : Hydration (water), Protein and Everything else, low carb,  avoid artificial sweeteners, avoid carbonated drinks,  have frequent smaller meals and avoid processed food.  Listen to you body as to what it tolerates and what it doesn’t. This is what I recommend for my patients.

I am not aware of any scientific evidence that proves any benefit to excessive amounts of fat for DS patients who have had their length of the common and alimentary bowels based as a percentage of the total length.

My recommendation are to have a well balanced high protein diet. I do not recommend a  low fat diet, except in the healing phase after surgery.  However,  there is no reason to consume excessive amounts of fat long term.

High fat diet is used to facilitate bowel movements for some patients who have constipation. It may be prudent to try and identify what may be causing the constipation and correct or eliminate them before one resorts to a very high fat diet as a “treatment” for constipation after Duodenal Switch. The possible causes for constipation after duodenal switch may be metabolic-organic (where some patients have infrequent bowel movements before DS, hypothyroidism), length of the common and the Alimentary channels and medications (pain meds, narcotics, antidepressants).

In addition, Medium Chain Fatty Acids do not require bile salts to be absorbed and are directly absorbed into the Portal Vein in the liver. Medium Chain Fatty Acids are not malabsorbed post Duodenal Switch. Medium Chain Fatty Acids included Caproic acid, Caprylic acid, Capric acid, and Lauric acid. Commonly found in varying amounts within coconut oil and palm oil. MCT supplement is made with Medium Chain Fatty Acids.

In summary,  I recommend that Duodenal Switch patients who have had surgery with our practice have a high protein balanced diet. I do not recommend avoiding fat, or going on a low fat diet.  I am not sure if there a reason to consume excessive amount of fat, which may in fact have unexpected metabolic and nutrient consequences.

Every patient, as their weight stabilizes, will find what works and what does not work for them. Some patients will tolerate a higher fat intake and other will not be able to tolerate higher fat intake.

Fancy Drinks and Iced Teas

February 27, 2014 3:00 am

Most of you may have heard me emphasize the importance of adequate hydration after surgery. At the same time I would be the first one to admit that drinking plain water gets old very quickly. I also do not recommend carbonated drinks (diet or regular). Most commercial products such as Crystal light also contain artificial sweeteners which in my opinion are to be avoided. Please note that there is extensive information here on my website on this topic.

One of the most benign looking drinks may be the refreshers that are available at Starbucks. An example of it is Very Berry Hibiscus Starbucks Refreshers™ Beverage.  It contains 21 g of sugar and 100 calories in a 24 ounce serving size.  Note that  it also contains 70-85mg of  caffeine.

Having some of these drinks on occasion  will do no harm.  However I would not recommend these drinks to replace water  as means of hydration. High content of  Caffeine can result in oxalate crystal formation. This predisposes a post weight loss surgical patient to much higher chance of kidney stone formations.

Sleeve Gastrectomy post operative diet

January 03, 2012 11:15 pm

A relatively common question asked post operatively regards the pace at which the post operative diet should be advanced. In our practice, patients are given a simple list describing 3 broad categories.  They are Bariatric 1, Bariatric 2, and Bariatric soft diet.
Each patient should advance his or her diet over a matter of 1-4 weeks in the post operative timeframe. The most important point to remember is that each one of us responds differently to the food at a certain point following surgery. The safest method to advance the diet would be to pay attention to what your body is telling you. If a patient is tolerating Bariatric 1 and Bariatric 2 diet, then they should be able to advance to a soft diet in one or two weeks. Alternatively, if the patient is having difficulty getting their required water on a daily basis, then advancing to a soft diet may be an incorrect move at that point. The basic order of food is water, protein, and everything else. This essentially means that a large salad is only
