People who've had
weight-loss surgery need to closely monitor their nutritional intake and may
require dietary supplements, according to the results of a small, new study.
Researchers looked at 23
patients who underwent gastric banding, a type of weight-loss procedure in
which an adjustable band is placed around the top of the stomach to create a
small stomach pouch.
nutritional counselling for three months after the procedure, many of the
patients had nutritional deficiencies. At least 86% did not get the recommended
daily amounts of vitamin D and calcium, a large number didn't get enough
protein, and many were slightly anaemic, the investigators found.
Issues regarding nutritional intake
"Our study clearly
shows that there are issues regarding nutritional intake in gastric banding
patients. They may need not only supplementation, but also counselling and
constant evaluation," study senior author Dr Abhimanyu Garg, chief of the
division of nutrition and metabolic diseases at University of Texas South-western
Medical Centre, said in a centre news release.
[weight-loss] surgery and the lifestyle changes necessary for continued success
are serious lifelong commitments," Dr Michael Lee, director of metabolic
and bariatric surgery at UT South-western, said in the news release.
"Dr Garg's study reinforces
the importance of careful patient selection and education in choosing banding,
sleeve, or bypass in addition to continued follow-up," Lee added.
Keeping your body healthy
Each year in the United
States, 150 000 to 160 000 people undergo weight-loss procedures, according to
the American Society for Metabolic and Bariatric Surgery.
Garg outlined a number of
ways for people to keep their bodies healthy after weight-loss surgery. Eating
more protein-rich foods will help meet protein requirements and also boost
intake of vitamins and minerals, and eating fatty fish will provide omega-3
fatty acids, he said.
Patients also need to eat
more fruits and vegetables, whole grains and nuts to ensure sufficient intake
of dietary fibre and should replace saturated and trans fats with vegetable
oils such as canola and olive oil to increase intake of monounsaturated fat,
It also a good idea to cut
back on processed foods in order to lower sodium intake, he said.
