Understanding Dehydration

Dehydration occurs when more water is lost from the body than the amount of water that is taken in.

Dehydration is a common struggle for those of us who have required colon removal. Without the colon, water is not absorbed properly and typically results in liquid stools. Many of us without a colon are also diagnosed with Short Bowel Syndrome. SBS further worsens the absorption of nutrition and water due to damage to or significant removal of the small intestine resulting in frequent diarrhea. Some individuals with SBS require lifelong TPN in order to meet their nutrition needs.

I was diagnosed with Short Bowel Syndrome as a child after part of my small intestine died from surgical complications of my colon removal. My SBS causes me to have a minimum of 20 stools in a 24 hour period - more if I am having a flare up. During a SBS flare, it is common for me to use the restroom as frequently as every 2-5 minutes for several hours at a time.

It is common for those with an ileostomy or Short Bowel Syndrome to experience stools soon after ingesting liquid further complicating our ability to take in adequate amounts of water.

Later, when I was in high school, it was discovered that I had a hole in my small intestine. As a result, I was placed on an NPO diet and started on TPN for my nutritional/hydration needs. I became accustomed to not drinking fluids due to the NPO diet while my intestine's hole was healing. I began to only drink fluid when I felt thirsty, which wasn't often. As an adult, I started being followed by a nephrologist a few years ago due to the discovery of cysts on my kidneys. While this could mean that I have Polycystic Kidney Disease, my nephrologist thinks it may just be due to years of dehydration. This has prompted me to truly make an effort at achieving and maintaining a state of hydration. In spite of my efforts of at times drinking 100+ ounces of water a day, my nephrologist states I remain in a dehydrated state.

For those with colon cancer causing conditions such as Familial Adenomatous Polyposis or Lynch Syndrome may also experience dehydration worsened by cancer treatments. Chemotherapy and radiation treatments may cause side effects including diarrhea, vomiting, and excessive urination that may result in dehydration. 


What are the signs of dehydration?

Common signs of dehydration include:

  • Headache
  • Dizziness or lightheadedness
  • Fatigue
  • Decreased urination
  • Dark yellow/amber colored urine
  • Decreased skin elasticity 
  • Dry mouth and mucous membranes (such as lips, gums, nostrils)
  • Muscle weakness
Severe signs of dehydration include:
  • Low blood pressure
  • Lack of perspiration
  • Sunken eyes
  • Increased heart rate
  • Fever
  • Delirium
  • Unconsciousness

Risks of Dehydration

If dehydration is severe and not rectified, an individual may experience:
  • Hypovolemic Shock - a reduction in blood volume that drops the blood pressure and amount of oxygen in the body. 
  • Increased risk to heart and cardiovascular system - blood volume decreases cause the heart to work harder and faster which increases blood pressure and heart rate. Sodium is also increased in the blood from dehydration resulting in blood thickening that over works the heart. 
  • Seizures due to electrolyte imbalance
  • Kidney issues such as kidney stones, UTIs, or even kidney failure. Water helps to remove toxins in the blood via urination. Dehydration can result in the build up of toxins and acids in the body.
  • Heat injury - ranging from mild cramps, heat exhaustion, heat stroke
  • Coma, Organ failure, and death may result from untreated dehydration

Diagnosing Dehydration

Several physical factors may be examined in addition to laboratory tests to identify common electrolyte changes associated with dehydration may be utilized for diagnosis. This may include:
  • Mental status exam
  • Vital signs
  • Temperature
  • Skin and mouth examination
  • Blood tests and urinalysis
  • Infants may also be examined for a sunken, soft spot on the skull, sucking mechanism, and loss of sweat and muscle tone

Treating and Preventing Dehydration

The U.S. National Academies of Science, Engineering and Medicine recommend men to drink 15.5 cups and women to drink 11.5 cups of water a day. It's recommended to limit or avoid caffeinated drinks.

An individual may need to adjust their daily water intake due to exercising, environment, overall health, and if they are pregnant or breastfeeding. 

IV fluids may be required for severe or recurring dehydration. This is common for those with malabsorption issues. 

There are several hydration products available to help prevent dehydration. Simply search for hydration drinks. Compare the amount of electrolytes and sugar in a drink when shopping. Some hydration products include:

  1. I have FAP, stomach cancer and severe dehydration. The dehydration and malabsorption have lead to mild heart problems. I make my own oral rehydration solution from a recipe from the Cleveland Clinic gut rehabilitation department. I also use Drip Drop and get 1-3 IV’s a week. A good explanation of the problems that come with dehydration.

    1. I've seen on occasion others posting their own drinks they've made from a recipe! How do you like it? I haven't tried it. I changed to Body Armor recently for my potassium and for improved hydration.

  2. Yeah, I also waiting for summer because of mangoes and vacations. But, whenever we go for a family trip with family then I never forgot to take some Ors Drink, because of my children or for myself also to save from the dehydration. This time, I would like to visit the beaches and sitting on the seaside.
