The doctors use a number of tests to diagnose anemia. Hb (hemoglobin) is one of the key indicators used in diagnosis. A hemoglobin test is a blood test that measures how much hemoglobin you have in your red blood cells. A hemoglobin test is generally used for detecting:

In addition, a hemoglobin test can also be carried out to assess bone marrow's response to treatment, evaluate possible blood donation and check the levels of red blood cells in the body. There are certain conditions that may interfere with the results of the hemoglobin test. In such cases, it is recommended to get the test done again.

For the hemoglobin test, a sample of your blood is taken and tested in a clinical laboratory [read more about the process here]. The results are expressed as grams of hemoglobin per deciliter (g/dL) or micrograms per liter (mcg/L). Normal range for this test is 12g/dL - 18g/dL (12.1-18.0 g/L) for adults and 9g/dL - 13g/dL (9.0-13.3 g/L) for children. If the test result comes out to be less than 7 gm, it can indicate a serious condition known as severe anemia. In some cases, the doctors may order follow-up tests to assess the current condition of the patient.

Apart from the hemoglobin test, certain other blood tests can be used for detecting low RBCs (RBC count) or abnormal types of RBC (red cell indices) or hemoglobin (Hb). These include complete blood count tests, reticulocyte tests, iron tests, and red blood cell indices.

In some cases, the doctor may opt to do a bone marrow aspiration and exam to check for any abnormalities in the bone marrow cells. In such cases, it of red blood cells is karyotype to rule out chromosomal disorders.

The most common reason for having an inadequate number of red blood cells in the body is an iron deficiency or anemia. Iron plays a significant role in the production of hemoglobin, which is responsible for carrying oxygen from the lungs to the tissues of other parts of the body. Hence, people suffering from iron are known as sickle cell trait. The tests include:

Complete blood count test - The complete blood cell count (CBC) is a routine test that checks the different components of your blood like number of red blood cells, white blood cells and platelets. It also has information about the size and hemoglobin content in each of these cells. A CBC includes tests for the following:

Reticulocyte test - This is a blood test that measures the reticulocytes (immature red blood cells) in the bloodstream. A high level of reticulocytes can indicate increased production of red blood cells by the bone marrow to compensate for anemia, or destruction of very early stage RBCs which are still unable to mature.

Iron tests - Iron is an essential component for RBC production. A test to assess the iron level in your blood is called a serum ferritin test, which measures the amount of iron stored in the body's cells and tissues. Another way to evaluate low iron levels is by carrying out a transferrin saturation test. In this case, the lab technician will extract serum from your blood sample and measure the amount of transferrin protein present in it. Transferrin is a protein that carries iron to the bone marrow where red blood cells are produced. Thus, if there is an insufficient amount of transferrin protein present in the serum, it shows that there is an inadequate level of stored iron.

Hemoglobin tests - A hemoglobin test is generally carried out to detect anemia, especially if the result of CBC tests are inconclusive. During this test, a small sample of blood is collected from your vein and sent to the laboratory for analysis. The test measures the amount of hemoglobin in your red blood cells.

Red cell indices - Red cell indices are tests that measure the size and hemoglobin content of the red blood cells. The values obtained from these tests can be used to detect anemia and other blood disorders.

Karyotype test - It is a lab test used to evaluate chromosomal abnormalities in red blood cells or bone marrow cells

Low blood cell counts also have other causes, such as infections or tumors. In some cases, low blood cells may indicate a more serious condition like bone marrow failure which requires immediate medical intervention to save the patient from death.

Thus, if you are suffering from any of these conditions and symptoms and suspect that you may be anemic, check with your doctor for the necessary tests to confirm or rule out your suspicions. Early detection and treatment of anemia can save you from serious complications like heart attacks, strokes, blood clots, etc.

Digestive System Disorders: Common Causes, Symptoms, and Prevention Tips

The digestive system plays a vital role in overall health by breaking down food, absorbing nutrients and eliminating waste. When this system does not function properly, it can lead to discomfort, poor nutrition and chronic illness. Digestive system disorders are increasingly common due to modern lifestyles, dietary habits and stress. Understanding their causes, symptoms and prevention strategies is essential for maintaining long-term gut health.

Public health research shows that a large proportion of adults experience digestive symptoms at some point in their lives, yet many delay seeking care until problems become severe.

 

What Are Digestive System Disorders?

Digestive system disorders are conditions that affect:

  • the oesophagus
     

  • stomach
     

  • intestines
     

  • liver
     

  • pancreas
     

  • gallbladder
     

They may be temporary or chronic and range from mild functional issues to serious inflammatory or structural diseases.

 

Common Digestive System Disorders

Acid Reflux and GERD

Gastroesophageal reflux disease (GERD) occurs when stomach acid flows back into the oesophagus.

Symptoms include:

  • heartburn
     

  • chest discomfort
     

  • sour taste in mouth
     

  • difficulty swallowing
     

Long-term reflux can damage the oesophagus if untreated.

 

Irritable Bowel Syndrome (IBS)

IBS is a functional bowel disorder.

Symptoms include:

  • abdominal pain
     

  • bloating
     

  • diarrhoea or constipation
     

  • alternating bowel habits
     

Stress and diet often trigger symptoms.

 

Constipation

Constipation involves infrequent or difficult bowel movements.

Causes include:

  • low fibre intake
     

  • dehydration
     

  • sedentary lifestyle
     

Chronic constipation affects comfort and gut function.

 

Diarrhoea

Diarrhoea results from rapid bowel movements.

Common causes include:

  • infections
     

  • food intolerance
     

  • medication side effects
     

Persistent diarrhoea may lead to dehydration and nutrient loss.

 

Peptic Ulcer Disease

Ulcers are sores in the stomach or intestinal lining.

Symptoms include:

  • burning stomach pain
     

  • nausea
     

  • bloating
     

They are often linked to infections or long-term medication use.

 

Inflammatory Bowel Disease (IBD)

IBD includes conditions like Crohn’s disease and ulcerative colitis.

Symptoms include:

  • chronic diarrhoea
     

  • abdominal pain
     

  • weight loss
     

  • fatigue
     

IBD requires long-term medical management.

Common Symptoms of Digestive Disorders

Digestive system disorders often present with:

  • abdominal pain or cramps
     

  • bloating and gas
     

  • nausea or vomiting
     

  • constipation or diarrhoea
     

  • heartburn
     

  • unexplained weight changes
     

Symptoms may fluctuate and worsen with stress or poor diet.

 

Causes of Digestive System Disorders

Poor Dietary Habits

Diets high in:

  • processed foods
     

  • refined sugars
     

  • unhealthy fats
     

strain the digestive system and alter gut microbiota.

 

Stress and Mental Health

Chronic stress affects gut-brain communication, worsening digestive symptoms.

 

Infections

Bacterial, viral or parasitic infections disrupt gut function.

 

Food Intolerances

Lactose, gluten or other intolerances cause digestive distress.

 

Sedentary Lifestyle

Lack of physical activity slows digestion and bowel movement.

 

Medication Use

Certain medications irritate the stomach lining or alter gut flora.

 

Who Is at Higher Risk?

People at increased risk include:

  • individuals with poor diet
     

  • those under chronic stress
     

  • older adults
     

  • people with family history of gut disease
     

  • individuals with sedentary lifestyles
     

Early lifestyle correction reduces risk significantly.

 

Diagnosis of Digestive Disorders

Evaluation may include:

  • medical history
     

  • physical examination
     

  • blood tests
     

  • stool tests
     

  • imaging or endoscopy
     

Diagnosis depends on symptom severity and duration.

 

Treatment Approaches

Medical Management

Treatment varies by condition and may include:

  • acid suppressants
     

  • anti-inflammatory medications
     

  • probiotics
     

  • antibiotics when needed
     

 

Dietary Modifications

  • increase fibre intake
     

  • limit trigger foods
     

  • eat regular meals
     

  • avoid excessive alcohol
     

Diet plays a central role in gut health.

 

Lifestyle Changes

  • manage stress
     

  • exercise regularly
     

  • stay hydrated
     

  • maintain sleep routine
     

Healthy habits support digestive function.

 

Prevention Tips for Digestive Health

Eat a Balanced Diet

Include fruits, vegetables, whole grains and lean proteins.

 

Stay Hydrated

Water supports digestion and prevents constipation.

 

Manage Stress

Mindfulness and relaxation techniques improve gut-brain balance.

 

Be Physically Active

Movement stimulates bowel activity and gut motility.

 

Avoid Smoking and Excess Alcohol

These irritate the digestive tract and worsen symptoms.

 

Seek Early Medical Advice

Early care prevents complications and chronic disease.

 

Long-Term Impact of Ignoring Digestive Problems

Untreated digestive disorders may lead to:

  • nutrient deficiencies
     

  • chronic inflammation
     

  • poor quality of life
     

  • increased disease complications
     

Early intervention is more effective and less invasive.

 

When to Consult a Doctor

Medical advice is recommended if:

  • symptoms persist beyond weeks
     

  • pain is severe
     

  • blood appears in stool
     

  • unexplained weight loss occurs
     

Prompt evaluation ensures safe management.

 

Conclusion

Digestive system disorders are common but often underestimated health issues. Symptoms such as bloating, pain, constipation and heartburn may seem minor initially but can signal deeper problems if ignored. Understanding causes, recognising early symptoms and adopting preventive habits help protect digestive health. With timely care, balanced nutrition and healthy lifestyle choices, most digestive disorders can be effectively managed, allowing the digestive system to function smoothly and support overall wellbeing.
