New Delhi : Experiencing high fever with stomach pain? It could be typhoid fever. Don’t ignore the symptoms—book Widal test to identify the cause early and begin the right treatment. Early diagnosis ensures faster recovery and prevents serious complications.
Experiencing a high fever accompanied by stomach pain can be both distressing and alarming. While such symptoms may sometimes be dismissed as signs of food poisoning or a viral illness, they could also point towards a more serious condition, which is typhoid fever. If you've been feeling unwell with persistent fever, abdominal discomfort, or other related symptoms, it's crucial not to ignore them. Instead, take a proactive step towards diagnosis. Book Widal test today to determine whether typhoid fever or another bacterial infection might be the cause.
Understanding the Widal Test
The Widal test is a simple blood test used to diagnose enteric fever, which includes typhoid and paratyphoid fevers. These illnesses are caused by Salmonella typhi and Salmonella paratyphi bacteria, which are usually transmitted through contaminated food or water. The test checks for specific antibodies that the body produces in response to infection by these bacteria.
The Widal test is highly valuable, especially in areas where typhoid is common and resources for more advanced diagnostic techniques are limited. By detecting antibodies in your blood, the Widal test can help your doctor confirm a typhoid diagnosis and begin appropriate treatment quickly.
Why You Might Be Experiencing High Fever and Stomach Pain?
While high fever and stomach pain can result from a variety of causes, typhoid fever remains one of the most frequent culprits, especially in tropical regions with poor sanitation. Some potential reasons for these symptoms include:
1. Typhoid Fever
A bacterial infection caused by Salmonella typhi, typhoid fever usually develops gradually, with symptoms intensifying over a few days. Along with fever and abdominal pain, it may also present with fatigue, loss of appetite, rash, and diarrhoea or constipation.
2. Gastroenteritis
This infection of the stomach and intestines may result from bacteria, viruses, or parasites. High fever may be present, but symptoms typically include nausea, vomiting, diarrhoea, and cramping.
3. Appendicitis
While usually accompanied by sharp, localised pain in the lower right abdomen, appendicitis can also begin with general stomach pain and fever. It requires urgent medical attention.
4. Urinary Tract or Kidney Infections
In some cases, urinary infections can cause high fever and lower abdominal pain. Left untreated, they may spread to the kidneys, worsening the symptoms.
5. Other Infections
Infections like malaria, dengue, or hepatitis may also manifest with abdominal discomfort and fever, highlighting the need for accurate testing and diagnosis.
Symptoms That May Indicate Typhoid Fever
If you are experiencing several of the following symptoms in addition to fever and stomach pain, it is especially important to book Widal test:
● Persistent high fever (often up to 104°F or 40°C)
● Abdominal pain or cramps
● Weakness and fatigue
● Loss of appetite
● Headache
● Constipation or diarrhoea
● Skin rash (rose spots)
● Body aches
● Sweating
● Confusion or lethargy (in severe cases)
These symptoms typically develop one to three weeks after exposure to the bacteria and may worsen if left untreated. Early testing and treatment are crucial to prevent complications.
How the Widal Test Works?
The Widal test detects agglutinating antibodies in the patient's blood that react against the O and H antigens of Salmonella bacteria.
Test Procedure:
● A healthcare professional draws a blood sample from a vein in your arm.
● The sample is tested in a laboratory to detect the presence and levels (titres) of antibodies.
● Results are usually available within 24–48 hours.
Interpreting the Results:
● A significant rise in antibody titre (usually fourfold) between two samples taken 7–10 days apart strongly suggests a current or recent infection.
● A single sample with high titres may also suggest infection but must be interpreted cautiously, especially in areas where typhoid is endemic.
● The results are best analysed in conjunction with clinical symptoms and other tests, such as blood culture.
Why You Should Book Widal Test Promptly?
Delaying diagnosis can worsen symptoms and increase the risk of complications such as intestinal perforation, internal bleeding, or systemic infection (septicaemia). Here’s why it's wise to book Widal test early:
● Confirms the presence of typhoid fever or rules it out.
● Enables timely treatment with appropriate antibiotics.
● Prevents complications and speeds up recovery.
● Reduces the risk of spreading the infection to others.
● Helps your doctor make informed decisions about further tests or hospitalisation.
What Happens After a Positive Widal Test?
If your Widal test results indicate typhoid fever, your doctor will usually prescribe antibiotics such as ciprofloxacin, azithromycin, or ceftriaxone, depending on resistance patterns in your region. Additional care may include:
● Hydration with fluids and electrolytes
● Adequate rest
● A soft, nutritious diet
● Monitoring for signs of complications
With proper treatment, most patients begin to feel better within a few days and make a full recovery within two to three weeks. However, it is essential to complete the full course of antibiotics to prevent relapse.
Prevention is Better than Cure
Typhoid fever is highly preventable. Once you’ve recovered or if your Widal test is negative, consider taking preventive steps to protect yourself and others:
● Drink clean, boiled, or filtered water.
● Avoid raw or undercooked street food.
● Wash hands regularly, especially before meals and after using the toilet.
● Get vaccinated, especially if you live in or plan to travel to high-risk areas.
● Practice good food hygiene when cooking or storing meals.
Conclusion
High fever accompanied by stomach pain is your body’s way of signalling that something may be wrong. While minor infections can cause these symptoms, it is vital not to overlook serious causes such as typhoid fever. Early diagnosis leads to better outcomes and prevents further complications.
