You likely gained weight after a colonoscopy due to temporary water retention (edema) from the procedure's fluids or inflammation, gas/bloating from the air used, decreased activity, and possibly eating heavier foods as you recovered; this weight gain is usually short-lived, but it's best to consult your doctor if you have concerns about persistent swelling or discomfort.
Weight Gain After Anaesthesia: What You Should Know
The effects of anesthetic agents on metabolism are usually short-lived, but they can cause fluid shifts and retention during recovery. After anesthesia, patients might notice swelling or bloating, which can contribute to an increased scale reading.
If you have any bloating or abdominal discomfort this may be from the air that was put into your bowel by the endoscopist during the examination. This is normal and should settle within 24 hours. If your discomfort doesn't settle, try to pass wind.
It is very common for patients to gain weight following any type of surgery. This is called edema or water retention. Edema is fluid that accumulates between the body's tissues as a result of plasma protein redistribution. It is the body's own normal response to trauma.
Patients often emerge from a colonoscopy with a “clean slate” in their intestines—but that also means a disrupted microbiome, weakened intestinal lining, and temporarily sluggish digestion. For some, bloating, diarrhea, cramping, or constipation may linger for weeks.
Preparing for a colonoscopy requires clearing the bowel with fasting, a laxative drink and, in some cases, and enema. While such preparation can alter the microbiome, the rich array of microbes that are present in the gut, research suggests that the microbiome bounces back in about two to four weeks.
Most individuals can resume light activities, such as walking or working from home, on the same day of the procedure, depending on how they feel. It is generally recommended to avoid strenuous exercise, heavy lifting, or consuming alcohol for at least 24 hours after the procedure to allow the body to recover fully.
If you gain 2 to 3 pounds a day, or 5 pounds a week, you should see your provider. It's also important to see them if you gain 5% or more of your body weight in a month. This type of unexpected weight gain may be a sign of an underlying health condition.
A reasonable interpretation of this relationship is that anesthesia-induced vasodilatation lowers the arterial pressure and, in turn, increases the intravascular retention of infused fluid by reducing the capillary filtration.
Bloating, or swelling due to a buildup of fluid in the tissues can cause weight gain. This may be due to menstruation, heart or kidney failure, preeclampsia, or medicines you take. A rapid weight gain may be a sign of dangerous fluid retention. If you quit smoking, you might gain weight.
Call your doctor or nurse advice line now or seek immediate medical care if: You have pain that does not get better, even after passing gas. You are sick to your stomach or cannot drink fluids. You have new or worse belly pain.
So, the more polyps you have, the higher your cancer risk. Someone with just one or two small polyps is generally at lower risk of having or developing colon cancer than someone with three to nine, or more.
Q: What should I expect during the prep? A: Feeling bloated, chilled and/or nauseous are common after the first few glasses, due to the large volume of fluid ingested. This is temporary and will improve once bowel movements begin.
In some people, particularly those who have been dieting or fasting, a meal that is high in carbohydrates, such as pasta or rice, can be stored as glycogen. Glycogen is stored with water, which causes an individual to gain water weight very quickly – as much as 2 pounds overnight.
THE REASON YOU SWELL
Another reason why swelling occurs is because general anesthesia tends to cause the blood vessels to dilate, and the blood vessels can leak fluid into the surrounding tissues. To be safe, most anesthesiologists administer more fluid than is needed, which compounds the swelling temporarily.
Most people will retain 8 to 15 pounds of excess fluid before they see leg and belly swelling. However, symptoms such as coughing and shortness of breath, loose stools, nausea and feeling full when without eating much may develop at the 5-to-7 pound mark" says Dr. Lewis.
Self-care options for fluid retention
It is a common misconception that being less active and resting while you recover from surgery requires fewer calories, it's quite the opposite. Surgery increases your body's need for calories so maintaining a good post-op diet with enough calories is essential.
Fluid retention in the body: If you experience rapid weight gain, this signals underlying conditions that impact the heart, liver, and kidneys, as well as an adrenal problem, polycystic ovarian syndrome (PCOS) and hypothyroidism. Poor sleep: Not getting enough quality sleep leads to weight gain.
If the weight fluctuation is very rapid (for example, a weight increase of 1-3 kg from one day to the next), it's definitely water, because fat doesn't accumulate that quickly! If it's water retention, swelling is often localized, manifesting as puffiness in the legs, ankles, hands, and abdomen.
The best time to weigh yourself is first thing in the morning after you've gone to the restroom but before you eat or drink anything. The reason for this is that your body has had enough time to digest all the food and drinks you've consumed from the day before all while you were getting your beauty sleep.
Complications Associated with Screening Colonoscopy
Puncture (perforation) in your colon or rectum. Worsening symptoms, such as hemorrhoids, chronic constipation, irritable bowel syndrome, or diverticulosis, caused by frequent bowel movements from the colonoscopy prep process.
Propofol works quickly; most patients are unconscious within five minutes. "When the procedure is over and we stop the intravenous drip, it generally takes only 10 to 15 minutes before he or she is fairly wide awake again.”
For up to a day after your colonoscopy, you may feel bloated and frequently pass gas to empty the air passed into your colon during your colonoscopy. Walking can help pass the gas out of your body and ease discomfort. You may not have a bowel movement for several days after your colonoscopy.
