Gastric Bypass and Gastric
Sleeve Diet
Immediately after your gastric bypass or gastric
sleeve surgery, you won't be able to eat for one
to two days. After a couple of days, you will be
able to eat some very specific foods according
to a diet progression. The purpose of the
gastric bypass diet progression is to help you
in the healing process, minimize stress on
surgical areas and allow time for your body to
adjust to new eating patterns.
Common phases in the gastric bypass and
gastric sleeve diet:
Phase I - Liquids - foods and fluids that
are liquid or semi-liquid at room temperature
and contain mostly water, such as broth, juice,
milk, strained cream soup and cooked cereal. In
most cases, you stay on a liquid diet for one to
two days.
Phase II - Pureed foods - foods with a
consistency of a smooth paste or a thick liquid.
Pureed foods contain no distinct pieces. The
pureed diet is generally followed for three to
four weeks, or as recommended by your dietitian
or doctor.
Phase III - Soft foods - foods that are
tender and easy to chew, such as ground or
finely diced meats, canned or soft, fresh fruit,
and cooked vegetables. You usually eat soft
foods for eight weeks before progressing to
eating foods of regular consistency with firmer
texture as recommended by your dietitian or
doctor.
During the diet progression, you eat many small
meals each day and sip liquids slowly throughout
the day (but not at the same time you eat). You
may start with six small meals a day, then
progress to four meals and then finally, when
following a regular diet, decrease to three
meals a day. Typically, each meal will include
protein-rich foods, such as lean meat, low-fat
dairy products (yogurt, cheese) or eggs. Protein
is important for maintaining and repairing your
body after surgery.
How quickly you move from one step to the next
depends on how fast your body adjusts to the
change in eating patterns and the texture and
consistency of food. People usually start eating
regular foods with a firmer texture three months
after surgery, but it can occur sooner.
CLEAR LIQUIDS
You may drink anything that is clear and liquid at room temperature. Avoid caffeine and carbonated drinks.
Examples:

adding lemon and adjusting the temperature. Please follow your doctors'
recommendations on how long to follow each diet.
