Diverticulitis is a condition where small, bulging pouches, called diverticula, that form in the lining of the large intestine become inflamed or infected. When a person experiences a flare-up of this disease, they typically focus on the severe abdominal pain and other gastrointestinal distress. While dizziness is not a primary symptom of the disease itself, it is a common secondary symptom that can arise from the body’s response to the infection or complications that follow. The feeling of lightheadedness or unsteadiness is frequently a signal that the underlying infection or inflammation is affecting the body’s overall systemic balance.
Understanding Diverticulitis and Its Primary Symptoms
Diverticulitis occurs when the diverticula, which are harmless pouches that protrude through the colon wall, tear or become blocked, leading to inflammation and often bacterial infection. The presence of these pouches without inflammation is known as diverticulosis, which is usually asymptomatic. Diverticulitis represents the acute phase of the disease, demanding medical attention.
The most recognized and immediate symptom of diverticulitis is persistent, intense pain in the abdomen, most often localized to the lower left side where the sigmoid colon is located. This pain can be sudden in onset or may gradually worsen over several days. Other common signs include a high temperature or fever, indicating a systemic infection is present, along with nausea and sometimes vomiting. Changes in bowel habits are also characteristic, presenting as either sudden diarrhea or significant constipation.
The Indirect Connection Between Diverticulitis and Dizziness
The systemic effects of a diverticulitis flare-up can rapidly lead to conditions that trigger dizziness, even though the primary problem is in the colon. One of the most frequent causes is dehydration, which is a direct consequence of the disease’s primary symptoms. Fever increases the body’s fluid loss through sweating, and accompanying symptoms like vomiting and diarrhea rapidly deplete both water and electrolytes.
This significant fluid loss directly reduces the overall blood volume within the body’s circulatory system. A lower blood volume can lead to orthostatic hypotension, a sudden drop in blood pressure that occurs when a person quickly stands up. When the blood pressure falls, not enough blood reaches the brain immediately, resulting in the sensation of lightheadedness or dizziness. Rehydrating the body is often the first step in alleviating this type of dizziness.
Beyond simple fluid loss, the body’s inflammatory response to the infection also contributes to this feeling of unsteadiness. When the body fights an infection, it releases inflammatory mediators that can cause blood vessels to dilate, or widen. This vasodilation, especially if widespread, can lead to a drop in overall blood pressure as the circulatory system expands.
The resulting low blood pressure means blood flow to the brain can be temporarily insufficient, particularly during changes in posture. In more severe cases, a systemic infection or sepsis can cause a dangerous and widespread drop in blood pressure, known as septic shock, which severely impairs blood flow to the brain and is always accompanied by dizziness and confusion. Therefore, the connection between the localized colon infection and dizziness is mediated through the body’s systemic response to inflammation and fluid imbalance.
Related Factors That Contribute to Dizziness
Dizziness during a diverticulitis episode can also be a side effect of the medical treatments used to resolve the infection. Antibiotics, which are frequently prescribed to clear the bacterial infection, can cause side effects such as drowsiness, nausea, or stomach upset that contribute to a general feeling of disorientation or lightheadedness. Similarly, strong pain relievers, particularly opioid-based medications sometimes used for severe abdominal pain, are known to induce dizziness and sedation.
Another less common, but serious, factor is internal bleeding and the resulting anemia. Although diverticulitis itself is an inflammation, diverticulosis can cause diverticular bleeding, which results from a blood vessel rupture within a pouch. If the bleeding is severe or prolonged, it can lead to a reduction in the number of red blood cells, a condition called anemia.
Anemia reduces the blood’s capacity to carry oxygen to the brain and other tissues, causing persistent fatigue and chronic dizziness. The population most affected by diverticulitis, typically older adults, may also have co-existing health issues that independently increase their risk of dizziness. Conditions such as high blood pressure, diabetes, or pre-existing heart disease can destabilize the circulatory system, making a person more susceptible to lightheadedness during the stress of a diverticulitis flare-up.
Recognizing When Dizziness Signals a Medical Emergency
While mild lightheadedness can often be managed with rest and hydration, dizziness accompanied by certain warning signs can indicate a severe and potentially life-threatening complication. Fainting, or syncope, is a signal that the brain is not receiving sufficient blood flow and requires immediate medical attention. Any sudden, severe disorientation or an inability to remain steady should be treated as an emergency.
Other concerning symptoms include dizziness coupled with chest pain, extreme shortness of breath, or a rapid, fluttering heart rate. These signs may point toward significant blood loss or a severe systemic infection like sepsis. The inability to keep any fluids down due to persistent vomiting, which prevents rehydration, also warrants immediate medical consultation. When dizziness occurs alongside severe, worsening abdominal pain or a high, unrelenting fever, it is a sign that the infection may be progressing and requires prompt professional care.
