Why BariNutrics™

In spite of the multiple clinical benefits, a number of nutritional complications can develop, especially in the long term which could cause serious detriment to a patient’s health”.

The BariNutrics™ philosophy is simple: leverage science to design tailored, high quality, highly absorbable supplements that meet the unique nutritional requirements of patients who have undergone bariatric surgery.

Bariatric weight loss surgery is a highly effective treatment to combat obesity and support sustained weight loss. In addition, it has been shown to mitigate other obesity-related conditions inducing the remission of type 2 diabetes, improving cardiovascular health, mood, fertility and alleviating joint pain. However, it is not without risk. While there are several different types of bariatric procedures, all interfere with nutritional intake and gastrointestinal absorption of nutrients to some degree, which can lead to a broad array of other health concerns. Therefore, all procedures require life-long nutritional insurance.

BariNutrics™ is committed to forming partnerships with patients who have chosen to undergo weight loss surgery, to provide them with life-long nutritional healthcare, as well as supporting the surgeons who help them.

Nutritional Deficiencies Occur With All Procedures

There are several different types of bariatric weight loss surgeries, all of which have been shown to increase a patient’s risk of long term nutritional deficiencies. Surgical procedures are generally classified into restrictive procedures, in which the stomach capacity is greatly reduced or malabsorptive procedures, in which malabsorption is the primary driver of weight loss. They may also involve a combination of both.

Gastric Sleeve

Gastric Bypass

The vertical sleeve gastrectomy (VGA or gastric sleeve) removes approximately 60 – 85% of the stomach, leaving the remaining portion of the stomach in a sleeve like shape. This is a restrictive procedure and nutritional deficiencies may arise due to reduced stomach volume, reduced dietary intake of nutrient-rich foods, decreased capacity for digestion, and reduced gastric acid affecting nutrient absorption.

Gastric Bypass

Gastric Sleeve

Worldwide, the Roux-en-Y gastric bypass (RYGB) remains the most commonly performed weight loss surgery.1 It involves separating off a small section of the stomach using surgical staples to create a short, pocket-shaped, pouch-like stomach. The bowel is then divided and re-joined in such a way that food is diverted from the stomach to a part of the bowel that is further along the digestive tract. This is a restrictive and malabsorptive procedures. Weight loss occurs as this part of the bowel is not efficient at absorbing fats and sugars. Nutritional deficiency may occur as sections of the digestive tract where optimal absorption of fat soluble vitamins and other minerals is bypassed.

Adjustable Gastric Band

Adjustable Gastric Band

The adjustable gastric band involves placing a band around the upper part of the stomach to make the stomach smaller. A silicon balloon is then placed inside the stomach to restrict stomach capacity. This is a restrictive surgery and nutritional deficiency may occur due to reduction in dietary intake and lowered tolerance for key nutrient-dense foods. This procedure is becoming less popular due to potential complications and the need for secondary operations.

Biliopancreatic Diversion with Duodenal Switch

Biliopancreatic Diversion with Duodenal Switch

The duodenal switch procedure reduces stomach size, reroutes the intestine and removes the gallbladder. This a malabsorptive procedure and nutrient deficiencies may arise due to reduced dietary intake, reduced stomach volume, significant malabsorption, reduced gastric acid and decreased digestive capacity.

The most common micronutrient deficiencies after surgery include calcium and vitamin D, folate, iron, B12, zinc and copper.2 This can lead to long-term complications such as osteoporosis, anaemia (and poor energy) and neurological problems. Patients may also commonly suffer deficiency of the macronutrient protein, which can lead to generalised weakness, and poor body composition.

A comprehensive multivitamin-mineral, calcium and vitamin D and protein regime can help to counteract nutritional deficiencies and their associated symptoms to optimise patient’s surgery results and keep them at functioning at their best into the long term. Unfortunately, many patients already present with a number of nutritional deficiencies prior to surgery – therefore may benefit from a nutritional top-up in time leading up to their surgery as well (Table 1).
