When we experience general health issues, such as a low-grade fever, sweating, fatigue, or unexpected loss of weight, it is important to visit a healthcare provider. However, a doctor might have difficulty identifying the underlying causes. Many symptoms are variable and nonspecific, depending on the person. More importantly, many diagnostic procedures can be costly and time-consuming to give us a clear and quick answer. In this article, we will take a look at the 10 most difficult diseases to diagnose.
1Celiac Disease
Celiac disease is a condition characterized by a reaction of the immune system to gluten. This leads to inflammation in your small intestine. Most flare-ups occur when you consume gluten-containing products like rye, barley, or wheat. On average, it takes around 6 to 10 years to diagnose celiac disease. The main reason is that many symptoms are quite similar to common digestive issues, such as heartburn, acid reflux, headaches, or itchy skin. A blood test and an endoscopy are two common tests to detect the presence of this condition. [1]
