Gastrointestinal diseases

It includes all the digestive disorders, which are detected and treated in light of modern medical technologies such as performing gastroscopy and colonoscopy

  • Peptic ulcers
  • Gastritis
  • cholelithiasis
  • Biliary colic

Also, many other diseases such as internal gastrointestinal bleeding can be diagnosed easily and patients can achieve treatment in a short time. In addition, to the upper and lower endoscopic examinations of the gastrointestinal system. However, the diagnosis of the diseases is confirmed through a CT scan and ultrasound examinations.

Some of the diseases and conditions that are diagnosed and treated in the Internal Medicine Unit:

Acute Respiratory Infections

It can be divided into two parts; The upper respiratory tract infections which affect (sinuses, nose, and throat), and the lower respiratory tract infections which affect (trachea, lungs, and bronchial tubes), usually caused by a virus during the autumn and winter seasons. Therefore, symptoms may vary depending on which system is affected.

Infectious Diseases

it involves a wide range of diseases such as skin infections, hepatitis, diarrhea, inflammatory diseases of the bones and joints, parasitic diseases, sexually transmitted diseases, influenza, and Brucellosis are diagnosed in internal medicine clinics. However, providing an isolated environment for these cases to prevent contamination during treatment.


It is also known as” High blood pressure”. Hypertension condition occurs when the blood pressure inside the body exceeds the normal values. However, The systolic blood pressure should be less than 140 mmHg and the diastolic blood pressure should be less than 90 mm Hg in adult individuals. Once the blood pressure is higher than these values, then this indicates a disease called hypertension. Moreover, It causes many problems such as blood vessel damage and bleeding, brain hemorrhage, kidney damage, and stroke. The treatment of hypertension aims to reduce these diseases as well as to reduce heart attacks.


A disease identified by high blood sugar levels. The levels of blood sugar are regulated by hormone actions called insulin. However, Diabetes occurs due to insufficient secretion of insulin, insulin resistance, or both. According to the type of diabetes, treatment may require drugs to make insulin more influential, slow glucose absorption from the gut, increase production of insulin, or daily insulin injections. As a result, lifestyle changes, such as exercise, dietary changes, and weight loss may also be effective.


Thyroid hormones T3 and T4 secreted from the thyroid gland have many important functions, especially the regulation of the body’s metabolic rate and body’s energy. Therefore, when this gland fails to produce enough amounts of these hormones, the metabolism of the body slows down. The problems with disrupted hormonal balance include fatigue, weight gain, dry skin, tiredness, inability to stay warm.

Although, it may results sometimes in thyroid cancers and autoimmune diseases may occur due to insufficient or deficient thyroid hormones. Therefore, thyroid diseases must be treated to bring back sufficient hormone levels

High blood cholesterol and triglycerides

Due to unhealthy and imbalanced nutrition, genetic factors and chronic diseases, levels of cholesterol and triglycerides in the blood may be higher than normal. The elevations in these parameters appear in routine blood tests, advanced elevations may present with symptoms such as the formation of sebaceous glands around the eyes. However, If blood lipids are not controlled with medication or nutritional therapy it may increase the risk of stroke and heart attack. Therefore, the treatment may involve weight loss, exercise, and a low-fat diet.

Gastrointestinal diseases

Diseases such as hepatitis, cirrhosis, liver cysts, gastroesophageal reflux disease (GERD), gastritis, ulcers, and hiatal hernia. cholecystitis and Gallstones.

Anemia and other blood diseases

Low levels or lack of enough red blood cells that carry iron, hemoglobin, and hematocrit is called anemia. The most common reason is an insufficient intake of iron, vitamin B12, and folic acid in the body as a result of insufficient and imbalanced nutrition. In addition, there are several types of anemia, including sickle cell anemia, thalassemia, iron deficiency anemia, aplastic anemia blood clotting disorders, bleeding, and bone marrow-related diseases.

Rheumatic Diseases

It includes many health problems and diseases resulting from the autoimmune system attacking healthy tissues, including muscles, joints, ligaments, and tendons. However, the bones are also affected by inflammation resulting from arthritis.
