ENDOCRINE DISORDERS & PHARMACOTHERAPY
The endocrine system consists of glands that produce hormones regulating metabolism, growth, reproduction, and many other vital functions. When these glands don’t work properly, it leads to endocrine disorders.
This guide explains three common endocrine disorders — Diabetes Mellitus, Hypothyroidism, and Hyperthyroidism — including their causes, symptoms, and management.
Diabetes Mellitus (DM):
What is Diabetes Mellitus?
Diabetes Mellitus is a chronic condition where the body either doesn’t produce enough insulin or cannot use it effectively. This leads to high blood glucose levels and long-term complications affecting multiple organs.
Main Types of Diabetes:
- Type 1 DM: Autoimmune destruction of beta cells; requires insulin
- Type 2 DM: Insulin resistance; most common type
- Gestational Diabetes: Occurs during pregnancy
Common Symptoms:
- Polydipsia (increased thirst)
- Polyuria (frequent urination)
- Polyphagia (excess hunger)
- Weight loss
- Fatigue and blurred vision
- Slow wound healing
Management of Diabetes:
Non-Pharmacological:
- Balanced diet with controlled carbohydrates
- Regular exercise
- Weight management
- Blood glucose monitoring
Pharmacological Treatment:
- Type 1 DM: Insulin therapy
- Type 2 DM:
- Metformin (first-line)
- Sulphonylureas
- DPP-4 inhibitors
- SGLT-2 inhibitors
- GLP-1 analogues
- Thiazolidinediones
Patient education regarding hypoglycaemia is essential.
Hypothyroidism:
What is Hypothyroidism?
Hypothyroidism occurs when the thyroid gland produces insufficient hormones, slowing metabolism.
Symptoms:
- Fatigue
- Weight gain
- Cold intolerance
- Dry skin and hair loss
- Constipation
- Depression
Management:
- Levothyroxine (drug of choice)
- Take on empty stomach
- Monitor TSH levels regularly
Hyperthyroidism:
What is Hyperthyroidism?
Hyperthyroidism occurs due to excess thyroid hormone production, increasing metabolic rate.
Symptoms:
- Weight loss
- Heat intolerance
- Tachycardia
- Anxiety and tremors
- Goitre
Management:
- Antithyroid drugs (Methimazole, PTU)
- Beta blockers for symptom control
- Radioactive iodine therapy
- Surgery (thyroidectomy)
Summary:
Endocrine disorders like diabetes and thyroid diseases require proper diagnosis and long-term management. Understanding pharmacotherapy ensures safe and effective patient care.
