Anemia, Fatigue, Weight Changes, and Digestive System Complaints

Medical Approach to Anemia, Fatigue, Weight Changes, and Digestive Complaints

Symptoms such as fatigue, weakness, unexplained weight loss, or digestive issues—often overlooked in society—can actually be warning signs of a serious systemic illness. Our internal medicine specialists aim to identify the root cause of the problem by examining these vague symptoms with the meticulousness of a detective.

Medical Evaluation of Fatigue, Anemia, and Weight Changes

Anemia, Fatigue, and Vitamin Deficiencies

Persistent fatigue and chills are often caused by anemia resulting from a deficiency in iron, vitamin B12, or folic acid. However, a specialist’s approach is not merely to replace the missing vitamin; it is to determine the “cause” of this deficiency (is it due to hidden bleeding in the gastrointestinal tract, or an absorption disorder?). The underlying cause is treated by conducting the necessary blood and stool tests.


Unexplained Weight Changes

If you are losing weight rapidly without dieting (suggesting cancer, hyperthyroidism, or uncontrolled diabetes) or gaining weight suddenly and uncontrollably (suggesting hypothyroidism, insulin resistance, or metabolic syndrome), this should not be dismissed as a simple dietary mistake; you should undergo a comprehensive internal medicine evaluation immediately.


Digestive System and Metabolic Complaints

Symptoms such as heartburn, acid reflux, bloating, indigestion, diarrhea, or chronic constipation may indicate conditions such as gastritis, reflux, peptic ulcers, fatty liver disease, or Irritable Bowel Syndrome (IBS). Following a physical examination and abdominal ultrasound, a medical diet and medication regimen are prescribed.
