The Colon: Common Problems & Surgery

What surgery and problems are common to the colon? The colon is a long tube-like organ that makes up most of the large intestine. It is one of the major parts of the digestive tract, responsible for the formation and disposal of our indigested stool.  Once the food enters into the small intestine and all the nutrients, it goes through many enzymes for nutrient absorption and then makes its entry into the colon. Here, the colon absorbs the leftover vitamins, water, and salts from the food, converting it into the fecal matter and excreting it as waste.

Common Problems of the Colon

Problems with the colon classify as abdominal issues since it makes up a huge part of the stomach. Having an irritable bowel is very common amongst people. A dysfunctional colon will often lead to constipation. The colon is responsible for the formation of your stool, the over absorption of water from the stool makes it hard and dry. Consequently, this causes the occurrence of constipation.

Apart from constipation, problems with the colon can also result in stomachaches, diarrhea, bloating, fatigue and stomach cramps. Thus, colon health is emphatic for an individual if they want to avoid abdominal discomfort.  The best way to maintain colon health is through dietary changes.

Colon Problems Surgery

Dietary Changes

The most common cause of bad colon health is a person’s dietary choice. Eating a diet that lacks nutritional value, especially fiber, can have adverse effects on the colon. Thus, the best way to deal with colon problems is to make changes to your diet.

Foods that put stress on a weak stomach include red meat, processed carbohydrates and sugar, alcohol, and coffee. The ideal food for colon issues is fresh vegetables and fruits. You should also consider foods that are high in fiber since fiber eases the passing down of food particles.

Types of Colon Disorders

The following are some of the disorders related to the large intestine. These problems are ordinary, especially amongst older men.

  • Diverticulitis (this is a disease that causes pouch formation inside the linings of the colon, it leads to disturbing symptoms and discomfort)
  • Crohn’s Disease (a person suffering from this disease faces intense pain in their abdomen)
  • Colorectal Cancer(this disease does not show any symptoms, however, it is very severe)
  • Irritable Bowel Syndrome(this disease causes frequent pain in the lower left side of the abdomen)
  • Ulcerative Colitis


Abdominal diseases and colon problems are now more common than they ever were. This is mostly because the general population leads an unhealthy lifestyle. Your gut health is a clear reflection of your lifestyle choices. Eating unhealthy food, and living a sedentary lifestyle can put you at high risk of colon problems.

This is why it is important to exercise and make the right nutritional choices.  A good intake of fibrous food allows for a smoother stool. Furthermore, it also decreases your risks of high blood pressure, obesity, hernias, hemorrhoids, and colon cancer. Moreover, smoking is also a leading cause of colon issues that you can avoid.

Colon Surgery

In extreme cases, lifestyle changes and medication are not enough for the intense colon pain. Instances such as these call for surgical measures to overcome colon pain. A patient needs surgery when the colon damage starts to affect the health and leads to life-threatening concerns.  In the case of inflammatory spread, surgery becomes the only option for the removal of the infected colon cavity.

Types of Colon Surgery

The choice of the surgical procedure depends on where exactly is the bacterial damage on the colon. Furthermore, the severity of the patient’s condition is the determining factor of the surgical technique. There are two approaches to colon surgery, open surgery or resection, and laparoscopic surgery.

Open Surgery

In this surgery, the surgeon uses a local excision technique. A simple procedure involves making a big incision on the abdomen so that they can operate on your stomach. Doctors can use this surgical approach regardless of the colon problems. The purpose of the surgery is to remove the part of the colon that under bacterial invasion.  The large cut on your abdomen allows the surgeon good visibility and room to clean the abdominal regions after removal.

Laparoscopic Surgery

A surgeon usually opts for this surgery when the patient is old or has other underlying conditions. This surgery is not invasive, because the incisions are smaller, therefore, a patient can recover from it much faster. In this surgery, the surgeon inserts a laparoscope inside the small incisions and into the abdominal cavity. This device is tube-like in shape, with a camera attached to its end and light for visibility.  This tool sends a clear picture to the doctor about the infectious spread on the colon.

Gallbladder Disease: Will You Need Serious Surgery?

Do you need serious surgery for gallbladder disease? A gallbladder is an organ that aids a person’s digestion by storing bile and releasing it in the small intestine. It’s a small organ located right under the liver, with a highly purposeful functionality in the body. Bile is a yellowish liquid that the liver makes and transfers to the gallbladder. This liquid helps break down tiny food particles in the small intestine. Furthermore, it also helps eradicate the waste material.

Types of Gallbladder Diseases

The number of complications of the gallbladder is immense. However, the most common medical issues include gallbladder disease. Gallstones and Cholecystitis are just some of the gallbladder diseases amongst many others.


Gallstones may be the most common gallbladder diseases of all time. This may be due to the average person’s diet since gallstones consist of cholesterol and solidified bile. It shares commonality because people are now more accustomed to eating cholesterol-rich food.

Gallbladder Disease Causes & Treatment


In this gallbladder disease, a person may or may not experience any distinctive symptoms. However, if the gallstone is in any of the openings, an individual can experience severe pain. They will feel a sudden striking pain between the belly button and the right rib.

Furthermore, other symptoms of the gallstones include:

  • Intense abdominal pain lasting several hours
  • Fever, along with chills
  • Itchiness sensation on the skin
  • Sweatiness
  • Dark coloration of urine
  • The pale color of stool
  • Yellowish color on the skin
  • Nausea
  • Vomiting
  • Loss of appetite
  • Muscular contractions inside the abdomen (this occurs when a gallbladder makes contraction to expel a gallstone)

When facing any of these issues, a person should stay away from foods that contain fat. In some cases, fatty foods act as triggers or initiators of abdominal discomfort. A person must be quick to visit a doctor if they experience pain or discomfort.

Gallbladder Disease Surgeons


This condition supersedes gallstones in terms of severity. When tiny gallstones start accumulating inside the gallbladder, they cause blockages inside the bile duct. These blockages tend to swell up over some time, and this swelling inside the bile duct is cholecystitis. It’s a condition that involves gallstones stuck inside the bile duct, causing blockages, swelling, and other serious complications.

In this case, instant treatment becomes a necessary endeavor. However, there are two stages of Cholecystitis, acute and chronic.

Acute Cholecystitis

Acute Cholecystitis is a condition in which a person experiences pain that lasts only about 6 to 12 hours. The severity of this condition depends on the frequency of the painful episodes. A doctor determines that a person has acute cholecystitis when their pain lasts for a week.

If the painful episodes start lasting beyond seven days, it is an indication that the condition is more severe and may lead to chronic cholecystitis. Other symptoms of this disease, in addition to pain, can involve vomiting, nausea, yellowing, swelling, and fever.

This disease also has other causes apart from gallstones. Major surgeries, inflammation, and illness can also spike cholecystitis in a person. Increased inflammation in the gallbladder has terrible impacts, including the rupture and damage of the gallbladder.

Chronic Cholecystitis

Long-term inflammation in the gallbladder causes Chronic Cholecystitis. In this condition, you can undergo serious complications, as the gallbladder fails to empty the gallstones, and they deposit further inside. This has serious outcomes. When gallstones block out the exit points inside the gallbladder, bile tends to accumulate excessively inside.

Therefore, stagnant bile fluid becomes vulnerable to infections and inflammation. Gangrene can occur inside the gallbladder, causing the tissues to die. This critical condition can also possibly burst or tear the gallbladder because of excess bile liquid.

Will You Need Surgery?

The decision of whether you need gallbladder surgery depends on the severity of your pain. It also depends on your underlying condition, health, and age. Surgeons take many considerations before they decide to send you into surgery.

Furthermore, you will be glad to hear that a gallbladder removal surgery is very safe and has no side effects. You do not even need your gallbladder. Thus, removing it will have no significant impact on your overall health.

If you are suffering from severe symptoms, the best option for you is to go into surgery. Hence, if you show up to the doctor with a series of gallbladder disease symptoms, they are likely to link you to professional gallbladder surgeons.
