Check these first

Feel the soil to see if it is too dry or too wet.
Inspect the undersides of the leaves for any signs of pests.
Check if the plant has outgrown its current pot.

Likely causes

Inconsistent Watering
Most likely
How to tell: Leaves turn yellow and drop off when the soil swings between being bone dry and soaking wet. The plant looks generally stressed.
What to do: Stick to a consistent schedule by checking the soil every 3 to 7 days. Water thoroughly only when the top inch of soil feels dry.
Nutrient Deficiency
Possible
How to tell: Older leaves turn yellow while the veins remain green. This often happens if the plant has been in the same soil for a long time.
What to do: Apply a balanced liquid fertilizer diluted to half strength once a month during the growing season. Do not overfeed, as this can burn the roots.
