Bariatric Surgery Candidate, Mineral Deficiency, Vitamin Deficiency

Brief summary

Patients undergoing bariatric surgery often develop new vitamin and/or mineral deficiencies or exacerbate prior deficiencies after surgery. Several bariatric supplement products exist including oral tablets and transdermal patches. The purpose of this study is to observe the concentrations of serum micronutrients and determine how many deficiencies develop in patients who use a transdermal patch.

Detailed description

Patients will undergo either a sleeve gastrectomy or gastric bypass procedure. All patients enrolled will have previously chosen to use the Patch MD MultiVitamin Plus patch for vitamin and mineral supplementation versus oral or other dosage forms of vitamins after surgery. A conversation between the patient and provider will occur first during a pre operative appointment, at which time the patient will be presented with the option to use oral vitamins or the Patch MD MultiVitamin Plus patch after surgery. Only if the patient chooses the patch will he/she be made aware of the study and recruited. Pre operative blood draws will be used to determine baseline micronutrient serum concentrations and existing deficiencies. The Gastrointestinal Symptom Rating Scale (GSRS) will be used pre operatively to determine baseline gastrointestinal symptoms. Post operative blood draws and GSRS data will be collected at 3 months, 6 months, and 1 year after surgery.

Design outcomes

Primary

MeasureTime frameDescription
Percentage of subjects with deficiencies1 yearThe primary end point is the percentage of participants who have two or more deficiencies of vitamins B1, B6, B12, folate, D, zinc, calcium, copper, and iron one year after bariatric surgery after using the Patch MD™ MultiVitamin Plus transdermal patch for supplementation.

Secondary

MeasureTime frameDescription
Thiamine1 yearThe average decrease in the serum concentration among all subjects
Pyridoxine1 yearThe average decrease in the serum concentration among all subjects
Methylcobalamin1 yearThe average decrease in the serum concentration among all subjects
Folate1 yearThe average decrease in the serum concentration among all subjects
Zinc1 yearThe average decrease in the serum concentration among all subjects
Calcium1 yearThe average decrease in the serum concentration among all subjects
Copper1 yearThe average decrease in the serum concentration among all subjects
Iron1 yearThe average decrease in the serum concentration among all subjects
Vitamin D1 yearThe average decrease in the serum concentration among all subjects
Parathyroid hormone1 yearThe average decrease in the serum concentration among all subjects
Total iron binding capacity1 yearThe average decrease among all subjects
Constipation syndrome1 yearThe average increase among all subjects using the Gastrointestinal Symptom Rating Scale. For constipation syndrome, three symptoms (constipation, hard stools, feeling of incomplete evacuation) will each be measured on a seven point Likert scale (0=no symptom, 6=most severe symptom). The three values will be averaged to provide one value which will represent constipation syndrome.
Diarrhea syndrome1 yearThe average increase among all subjects using the Gastrointestinal Symptom Rating Scale. For diarrhea syndrome, three symptoms (diarrhea, loose stools, urgent need for defecation) will each be measured on a seven point Likert scale (0=no symptom, 6=most severe symptom). The three values will be averaged to provide one value which will represent diarrhea syndrome.
Indigestion syndrome1 yearThe average increase among all subjects using the Gastrointestinal Symptom Rating Scale. For indigestion syndrome, five symptoms (nausea, stomach rumbling, feeling bloated, burping, and passing gas) will each be measured on a seven point Likert scale (0=no symptom, 6=most severe symptom). The five values will be averaged to provide one value which will represent indigestion syndrome.
Acid reflux syndrome1 yearThe average increase among all subjects using the Gastrointestinal Symptom Rating Scale. For acid reflux syndrome, two symptoms (heart burn and acid reflux) will each be measured on a seven point Likert scale (0=no symptom, 6=most severe symptom). The two values will be averaged to provide one value which will represent acid reflux syndrome.
Abdominal pain syndrome1 yearThe average increase among all subjects using the Gastrointestinal Symptom Rating Scale. For abdominal pain syndrome, two symptoms (stomach ache and hunger pains) will each be measured on a seven point Likert scale (0=no symptom, 6=most severe symptom). The two values will be averaged to provide one value which will represent abdominal pain syndrome.
Ferritin1 yearThe average decrease in the serum concentration among all subjects
