Understanding IBD symptoms can help with prompt diagnosis, effective treatment, and improved quality of life. Recognizing common symptoms of IBD and seeing a doctor can help you find the best way to manage your symptoms, depending on the cause.

IBD includes both Crohn’s disease and ulcerative colitis. Though there is no cure for these conditions, getting prompt treatment for your symptoms can massively improve your day-to-day life.

IBD conditions involve inflammation of the gastrointestinal (GI) tract and can cause a wide range of symptoms, varying in intensity and duration. Though symptoms can vary, these conditions often affect specific areas of the body.

We take a look at some of the most common IBD symptoms and how they may vary among different IBD subtypes.

Doctors will consider certain symptoms along with medical tests when diagnosing IBD. The main symptoms of IBD include the following:

Abdominal pain and cramping

One of the hallmark symptoms of IBD is abdominal discomfort, often accompanied by cramping.

In Crohn’s disease, this pain is typically located in the lower right abdomen, while in ulcerative colitis, it may be more generalized or confined to the left side of the abdomen.

The pain is usually caused by inflammation or ulceration in the intestines and can range from mild to severe.

You may also experience bloating.

Diarrhea

Diarrhea is a common symptom of both Crohn’s disease and ulcerative colitis, especially during flare-ups. This is often accompanied by urgency, where you feel an immediate need to use the bathroom.

In ulcerative colitis, diarrhea may contain blood or mucus.

In Crohn’s disease, diarrhea may be accompanied by undigested food particles, depending on the location of the inflammation.

Blood in the stool

Blood in the stool is a prominent symptom of IBD, especially ulcerative colitis.

It often appears as bright red blood or dark, tarry stools, depending on the severity of the condition and the extent of ulceration. This is a sign of active inflammation and may also be associated with rectal bleeding.

Blood may appear in the stool with Crohn’s disease, but this is less common and typically occurs when there is significant intestinal damage.

If you experience blood in your stool, it’s important to see a doctor promptly.

Weight loss and malnutrition

Chronic inflammation interferes with nutrient absorption and can lead to malnutrition.

This is particularly true in Crohn’s disease, where the inflammation can affect any part of the gastrointestinal tract, including the small intestine, which plays a crucial role in nutrient absorption.

This, combined with reduced appetite and frequent diarrhea, can result in significant weight loss.

Work with your doctor to find ways to make sure you meet your nutritional needs with Crohn’s disease or ulcerative colitis.

Fatigue

Chronic fatigue is a persistent symptom of IBD.

The ongoing inflammation, combined with nutritional deficiencies and disrupted sleep due to nighttime symptoms, can all contribute to feelings of exhaustion.

Fatigue can be further exacerbated by anemia, which can result from blood loss or malabsorption of iron.

Though it may seem like a somewhat vague symptom, it’s important to mention it to your doctor, along with your other symptoms, to ensure they get a full picture of what you are experiencing.

Fever

During active flare-ups, fever is a common symptom of IBD. This typically indicates inflammation in the body and may be associated with infection if a complication such as an abscess or fistula develops.

A persistent low grade fever is often seen in Crohn’s disease, whereas ulcerative colitis may lead to a higher fever during acute exacerbations.

Urgency and tenesmus

Tenesmus is the feeling of needing to pass stool even when the bowels are empty, and it is a common symptom of ulcerative colitis.

It can lead to frequent and uncontrollable urges to use the restroom, creating significant distress and disruption to daily life.

You may also experience painful or incomplete bowel movements along with this symptom.

While the primary symptoms of IBD affect the gastrointestinal system, IBD can also cause symptoms and complications that involve other parts of the body.

These may include:

Symptoms outside the gut are common in IBD patients and may make diagnosis and management harder. You may hear these symptoms referred to as “extraintestinal manifestations”.

However, documenting your symptoms and speaking with your doctor regularly to address any concerns can help you manage IBD and improve your quality of life.

Symptoms of IBD can be varied and impact different aspects of your body.

Recognizing the signs of IBD early — such as persistent abdominal pain, diarrhea, weight loss, and fatigue — can lead to prompt treatment and a better quality of life.

If you experience symptoms of IBD, it is important to consult your healthcare professional for prompt evaluation and possible treatment options. Keeping a journal of your symptoms can help you easily relay them to your doctor and may help you identify potential patterns.

If you are already having treatment for IBD, but your symptoms persist or are unmanageable, it may be necessary to switch to another medication under the guidance of your doctor.
