Colon cancer nutritional recommendations

Dietary advice for colon cancer post-surgery

Consequences and nutritional alterations post-surgery

Obviously the severity of the involvement is always directly proportional to the amount of tissue removed and its location.

Nutrient Absorption

When the bolus reaches the colon, the absorption of nutrients decreases considerably, so a resection of this, does not suppose a great loss in the level of nutrient absorption.

On the contrary, it supposes a very important loss in level of electrolytes and water, seriously affecting the hydroelectric balance of our body.

This is because the small intestine absorbs most of the water ingested. The same applies to chloride, sodium and potassium electrolytes.

Absorption of water and electrolytes

The colon is responsible for absorbing about 90% of water, and electrolytes such as chloride, sodium and potassium, which the small intestine has not been able to absorb previously.

Thus, if he has been removed (totally or partially), it will not be able to perform this function, or it will be reduced and will most likely have significant diarrhea, among other symptoms:

Fibers and their fermentation

Some substances are not digested by the small intestine, such as some carbohydrates that resist the action of enzymes in the small intestine and pancreas.

Fibers reach the colon as oligosaccharides and polymers, where they will be fermented by the bacterial flora that resides in it. It will form a series of short chain fatty acids, gases and alcohols. Part of them will be reabsorbed and, finally, the feces will be formed.

Obviously, total or partial excision of the colon will also affect this fermentation and subsequent absorption, especially in resections of the cecum, ileostomy and total colectomy.

For this reason, food and intake of liquids must be based on the reduced capacity of nutrients absorption, so that patients to be able to absorb as much nutrients as possible, both solids, liquids and gaseous.
