The disorder most commonly known as Crohn’s disease is a form of inflammatory bowel disease (IBD). It makes the tissues of the digestive tract inflamed, which can cause stomach pain, severe diarrhea, fatigue, weight loss, and not getting enough food.

Crohn’s disease can cause inflammation in different parts of the digestive tract, but most of the time it affects the small intestine. This inflammation is generally found to spread to the bowel’s deeper layers. Crohn’s disease is not only painful and hard to live with, but it can also endanger your life.

Inflammatory bowel disease (IBD), which includes Crohn’s and the condition known as ulcerative colitis (UC), is a class of diseases. UC also causes inflammation, but solely in the colon, unlike Crohn’s.

There is no known cure for Crohn’s disease, but medicines can make the symptoms much less severe and can even cause long-term remission and healing of the inflammation. Many individuals with Crohn’s disease are able to function well after receiving treatment.

There are still no proper reasons or recognized causes for Crohn’s disease. Diet and stress were once thought to cause Crohn’s disease, but now doctors know that they only make the condition worse. Its development is likely influenced by a number of things.

The body’s defense system:

Crohn’s disease might be brought on by a virus or bacterium, although this hasn’t yet been determined by researchers. When your immune system fights off bacteria or an environmental trigger, it may attack digestive tract cells as a strange immune response.


Since Crohn’s disease tends to run in families, genes may make a person more likely to get it.

Any portion of your small or large intestine might be affected by Crohn’s disease. It could consist of many segments or be continuous. In certain individuals, the sickness is limited to the colon, which is a portion of the large intestine.

The severity of Crohn’s disease symptoms can range from minor to severe. Usually, they develop gradually, but occasionally they appear suddenly and without notice. You may also experience periods without signs or symptoms (remission).


When the condition is active, the following symptoms are typical:

  • Diarrhea\sFever\sFatigue
  • Iron deficiency (anemia)
  • Liver inflammation
  • Abdominal pain and cramping
  • Mouth ulcers,
  • Bile duct inflammation
  • Kidney calculi
  • Appetite suppression and weight reduction
  • Blood in the feces
  • Growth retardation or sexual maturity in children
  • Pain or leakage at or around the anus caused by an inflamed skin tunnel (fistula)
  • Inflammatory conditions of the eyes, skin, sinuses, and joints
  • Weight loss

Crohn’s disease is an inflammatory disease, so it often causes problems in other parts of the body as well. Let’s explore each of them to comprehend it in a simplified manner.

Digestive System:

The location of the disease and its severity both affect the symptoms. You may have a time when your symptoms are worse, called a “flare,” followed by a time when your symptoms are mild or go away, called a “remission.” Five years after being diagnosed with Crohn’s and getting treatment, almost half of those with the disease is in remission or only have mild symptoms.


One of the most prevalent signs of Crohn’s disease is this. The intestines cannot absorb as much liquid and nutrition when they are irritated. Your stools become watery and loose. More trips to the restroom could be necessary.


Ulcers in Crohn's patients

Ulcers are open sores that are brought on by chronic inflammation. The mouth, intestines, and anus are just a few of the places throughout the digestive tract where they might occur. Large ulcers can bleed, which might result in bloody feces.


Sometimes ulcers can penetrate the intestine’s wall. This makes a tunnel between two organs that wouldn’t typically join, like the skin and intestine. This is referred to as a fistula. They may exhibit signs like a painful skin bump or urinary tract infections. Fistulas can develop in up to 50% of Crohn’s patients over time.


Even though diarrhea is more typical, Crohn’s disease can also lead to constipation. It may be challenging to pass feces if the lower colon is inflamed. The issue might also be brought on by some medications, such as painkillers and iron supplements.


A digestive fluid called bile is transported from the liver and gallbladder to the small intestine by bile ducts. These ducts may occasionally become inflamed as a result of Crohn’s disease. It’s referred to as cholangitis. Fever, chills, and upper right abdominal pain are possible side effects.

Gall stones

Your risk of gallstones may virtually double if you have Crohn’s disease. Bile deposits that resemble rocks are there. In the small intestine, bile is digested. It might not absorb all of the salts in bile if Crohn’s disease harms that area. This may result in a buildup that eventually becomes gallstones.

Kyle Stones

Your small intestine is less able to absorb fat when you have Crohn’s disease. Your kidneys develop tough deposits as a result of these fats’ interactions with calcium.

Bile Duct Cancer

Cancer may develop from persistent bile duct irritation. The risk of bile duct cancer is actually nearly tripled by Crohn’s disease. A yellow tinge to your skin and eyes, scratchy skin, white feces, and weariness are all warning signs.


Inflammation of the liver may result from Crohn’s. It becomes a severe liver condition in about 5% of cases. Untreated sickness has the potential to leave lasting scars. It is cirrhosis. Due to cirrhosis, your liver may not function effectively, which can cause fatigue, appetite loss, swelling in the feet, legs, or ankles, and itchy skin.

Joint Disorders:

Up to 30% of IBD sufferers also have joint issues. There are two primary types:

Arthralgia: Joint discomfort without inflammation

Arthritis: joint discomfort with inflammation Joint swelling and reduced flexibility are symptoms of arthritis.

Most patients with arthritis are elderly. But it can also happen to those who have Crohn’s disease earlier in life.

The primary varieties include:

Axial Arthritis

Typically, the big joints of the arms and legs, including the knees, wrists, and elbows, are affected by this arthritis. The discomfort may shift from one location to another. The majority of times, there is no lasting harm.

Bone Arthritis

Lower back discomfort and stiffness are present here. Your range of motion may be restricted by the fusion of your bones.

Ankylosing Spondylitis

This condition, a more severe form of spinal arthritis, can cause inflammation of the heart valves, eyes, and lungs.

Spondylitis due to Cohn's disease

Cardiac Disease

Your risk of cardiac issues increases if you have Crohn’s disease. Research shows that IBD raises the chance of both heart attacks and heart disease by more than 20%.

Even though scientists are still looking into the link, they think that the following things are to blame:


Inflammation levels are higher in the bodies of Crohn’s patients. Plaques that obstruct arteries grow more quickly as a result of chronic inflammation. These plaques’ fragmentation can result in blood clots that result in heart attacks and strokes.


Anemia, a disorder in which there aren’t enough red blood cells to deliver oxygen, affects one in three patients with Crohn’s disease. To compensate for the deficiency in oxygen, your heart must pump more blood. This may result in heart failure, cardiac failure, or an enlarged heart.


If you take steroids for a long time, you may be more likely to get heart disease or heart failure.

Consult a physician right away if you experience any symptoms of heart disease, such as tightness or pain in the chest, breathlessness, or pain or weakness in your arms or legs. Many times, the signs of a heart problem aren’t clear, so you might not know you have one until you have a heart attack or stroke.

It’s crucial that you discuss your heart health with your physician. Your inflammation needs to be under control. The peak period of a flare is when your risk of a heart attack or stroke is greatest. You’ll need to take care of your anemia. Your doctor may advise you to take iron or vitamin B12 supplements.

Eye Condition

IBD patients with Crohn’s disease account for 10% of the population. The inflammation may impact the eyes, making them uncomfortable, puffy, and red. Consult your doctor if you experience any eye issues. One of the following conditions could exist for you:


Crohn's and Uveitis

Uveal inflammation is a disorder that affects the central layer of the eye wall. This results in discomfort, redness, hazy vision, and light sensitivity. For those with IBD, uveitis is the most frequent eye condition. The irritation can be reduced with steroid eye drops.


Episcleral tissue inflammation can cause minor redness and pain in the outer layer that covers the whites of your eyes. Although it frequently goes away on its own, your doctor may advise anti-inflammatory eye drops or medication to treat painful or persistent cases.

Warm eye

To produce high-quality tears, your eyes need vitamin A. If you have Crohn’s disease, your vitamin A levels may be low, which could make it hard for you to make or keep tears. This dryness may result in infection, burning, and itching. Artificial tears are calming, and vitamin A pills can help with the disease.


On the corneal margin, white deposits develop in keratopathy. This syndrome may be triggered by dry eyes and uveitis. Since keratopathy does not impair vision or cause discomfort, it is typically left untreated.

Skin Conditions

Skin issues, such as rashes, pimples, and more, are common in people with Crohn’s disease.

Common ailments include:

Erythema nodosum

This skin problem affects between 2% and 10% of patients with IBD. It results in painful, flaming lumps on the ankles or shins. On the arms, occasionally. They frequently appear during or just prior to a flare. Your doctor may change the dosage of your medications to reduce the underlying inflammation.

pyoderma gangrene

The first sign of this illness is small blisters, most often on the ankles and shins. A sizable, uncomfortable open sore could result from their combination. When the symptoms of your Crohn’s are under control, these sores usually start to heal. Antibiotics, injections, and ointments that you use topically are used to treat them.

Anal Fissures

Your anus may develop minor, uncomfortable fissures or rips as a result of Crohn’s. Ointments and warm baths can help relieve the pain.

Skin Tags

These are very small skin growths. They commonly occur close to the anus in Crohn’s disease. The skin may expand and develop into tiny flaps as fissures or swellings heal. Skin tags aren’t harmful, although they might itch if moisture or feces get caught in them. In order to avoid itching, keep the region clean.

Ticker Sores

During a flare, a few mouth ulcers may appear. They typically show up around the base of the tongue, along the sides, or between the gums and lower lip. The pain can be reduced by using a pharmaceutical mouthwash.


Anti-TNF drugs like adalimumab and infliximab can cause a rash that looks like psoriasis. Sulfasalazine can cause a rash that looks like an allergy. The palms, feet, scalp, and area behind the ear are the typical locations.

Thin skin, Acme, and Stretch marks

Skin problems might result from using steroids for an extended period of time.

Bone Disorders

Crohn’s disease might make your skeleton more brittle. Up to 60% of those who have Crohn’s or UC have decreased bone density compared to normal. Others suffer from osteoporosis, which causes their bones to thin. Others have osteopenia, reduced bone density, osteomalacia, or softening of the bones. All of these conditions can make it more likely that you will break or fracture a bone.

Later in life, some bone deterioration is typical. Old bone tissue is continually removed by your body and replaced with new bone tissue.

You begin to lose bone more quickly than it can be replaced after the age of 35.

But Crohn’s disease may quicken this process in the following ways:


Your bone turnover is hampered by the same inflammatory substances. You run a higher chance of developing osteoporosis if your flares are frequent.


Long-term use of these painkillers has been linked to weakened bones. Both the generation of bone-forming cells and calcium levels are decreasing.

Deficiency in Vitamin C

To absorb calcium, which builds bones, your body requires vitamin D. The small intestine is where vitamin D is metabolized; therefore, if Crohn’s disease affects that organ, you might not obtain enough of the vitamin. This may result in bone loss.

To stop bone loss, your doctor may tell you to use steroids less or give you a different drug. To stop bone loss or promote development, you might also need to take medicine.

Reproduction Issues

Menstrual cycles can be impacted by Crohn’s disease. You can experience more, fewer, or no periods at all. The term “electronic commerce” refers to the sale of electronic goods.

According to experts, inflammation can prevent regular hormone action. Your menstrual cycle may become irregular as a result of stress and poor nutrition. Your Crohn’s symptoms could get worse due to fluctuating hormone levels.

Issues With Fatigue

Crohn’s disease frequently manifests as fatigue. You feel worn out despite getting a lot of rest. For a variety of reasons, Crohn’s disease makes you feel excessively exhausted:


Fatigue may result from the brain being affected by chemical signals from inflammation.

Effects of medications

Antidepressants and methotrexate, two medications you take for Crohn’s, can make you feel drained or lethargic. Sleep disruptions could result from steroids.

Necessities of nutrition

Weakness is associated with low levels of folate, B12, and iron. They can also cause anemia, which results in a deficiency of blood cells that transport oxygen to the rest of the body. You can feel exhausted as a result of this.

Sleep issues

You may have trouble sleeping due to symptoms like pain and anxiety.

Mental Health

Crohn’s disease patients commonly experience occasional sadness or anxiety. It is tough to deal with the disease’s discomfort and symptoms. Although they do not cause Crohn’s, these feelings can exacerbate symptoms and induce flare-ups.

Therefore, it’s critical to look after your needs.

Care for your body is a necessary part of managing Crohn’s disease. But it’s just as crucial to take care of your emotional health. Self-care on a regular basis helps prevent you from feeling overly worried or overwhelmed.
