There are many diseases of the endocrine system, resulting from malfunctions of this complex system.

Here are some of the most common conditions and symptoms:  


1. Diabetes                                                        

One of the most widespread disorder of the endocrine system, diabetes, is a disease in which the pancreas does not produce enough insulin hormone or the body does not effectively use the insulin it produces. Because insulin is essential in helping the body to convert sugars and starch into energy, there may be serious consequences if diabetes is left undiagnosed and untreated.           

 Diabetes – symptoms:
- Excessive thirst or excessive hunger                                                    

- Fatigue                                                       

- Frequent urination                                   

- Nausea and vomiting                             

- Unexplained weight loss or weight gain           

- Changes in vision   


2. Polycystic ovary syndrome        

Polycystic ovary syndrome is also a common disorder of the endocrine system that affects between 7% and 10% of women between the ages of 15 and 45. This syndrome is a condition associated with symptoms of irregular menstruation, excess of male hormones, as well as acne and the difficulty of getting pregnant. They have an increased risk of metabolic complications such as diabetes and high blood pressure.

Polycystic ovary syndrome – symptoms:

- Irregular menstrual periods or lack of menstruation

- Infertility                                                           

- Excess of facial or body hair

- Hair thinning                                                  

- Issues with body weight                         

- Skin problems: acne on face, chest and back; pigmentation and thickening of the skin in the neck, abdomen and armpit areas.                                                                  


3. Thyroid                                                  

Thyroid hormones, which are produced by the thyroid gland, influence almost all body organs. Thyroid gland problems include hyperthyroidism (too much thyroid hormone), hypothyroidism (too little thyroid hormone), thyroid nodules, thyroid cancer.                                                                          

Hyperthyroidism – symptoms:

- Diarrhea                                                            

- Insomnia                                                           

- Fatigue                                                               

- Goiter (thyroid enlargement)
- Intolerance to heat

- Nervousness and easy transition from a mood to another

- Rapid heartrate (tachycardia) or palpitations (irregular beats)                      

- Unexplained weight loss                            

- Weakness (loss of power)


Hypothyroidism - symptoms:
- Cold intolerance                                     

- Constipation                                             

- Dry hair                                                     

- Fatigue                                                      

- Goiter (thyroid enlargement)    

- Muscle and joint pains                                             

- Lack of menstruation                                      

- Slow heartrate                                                

- Swelling of the face                                        

- Unexplained weight gain                                         


4. Osteoporosis                                               

This occurs in both women and men although the chance for women to develop this disease is four times higher. It is a condition in which the bones become fragile and more prone to breaking.
This may be the result of several factors, including a decrease in estrogen hormone (during menopause in women), or a decrease in testosterone levels in men (with age).

Because osteoporosis often has no obvious symptoms, it is often left undiagnosed until the affected person suffers a fracture or breaks a bone during a minor trauma or when significant bone pain occurs at an advanced stage of the disease.

Osteoporosis – symptoms:
- Back pain caused by fractured or compressed vertebrae                              

- Loss of height over time                                

- Bending of the back                              

- Bone fracture caused by minor trauma


A consultation with the endocrinologist can help you identify the cause and
establish a correct diagnosis. Left untreated, endocrine disorders can have serious effects on the functioning of the body.
