3. Fatigue: General fatigue or weakness can occur, especially if proteinuria is associated with kidney disease or other systemic conditions[3].

4. Hypertension: Elevated blood pressure may be present, particularly in cases where proteinuria is linked to chronic kidney disease or nephrotic syndrome[4].

5. Weight Gain: Sudden weight gain can occur due to fluid retention, which is often a consequence of significant protein loss through the urine[5].

Additional Symptoms

• Nausea or Vomiting: These symptoms may arise if proteinuria is part of a broader renal impairment or systemic illness[6].
• Changes in Urination: Patients may experience changes in urinary frequency or urgency, depending on the underlying cause of proteinuria[7].

Patient Characteristics

Certain patient demographics and characteristics may predispose individuals to proteinuria:

1. Age: Proteinuria can occur at any age but is more common in older adults, particularly those with chronic conditions such as diabetes or hypertension[8].

2. Gender: Some studies suggest that men may be more likely to experience proteinuria than women, particularly in the context of certain kidney diseases[9].

3. Underlying Conditions:
   - Diabetes Mellitus: A significant number of patients with diabetes develop diabetic nephropathy, leading to proteinuria[10].
   - Hypertension: Chronic high blood pressure can damage the kidneys, resulting in protein leakage into the urine[11].
   - Autoimmune Diseases: Conditions such as lupus or vasculitis can also lead to proteinuria due to kidney involvement[12].

4. Lifestyle Factors: Obesity, smoking, and sedentary lifestyle can increase the risk of developing conditions that lead to proteinuria, such as diabetes and hypertension[13].
