1. Yellowing or Thickening Nails
A yellow color to your nails is much more noticeable than other changes, which is important, because it is definitely something to pay attention to. Generally, if your nails become yellow or thicker than usual, this means a fungal infection. This can be accompanied by pain or other discomforts, and in this case, you should definitely schedule a visit with a doctor.
Most topical medicine doesn’t usually do much for the infection since it affects the nail bed and deeper, so you may need an oral medicine prescribed by a doctor. The prescription medicine does come with adverse side effects which are featured on the label. However, there are newer treatment options available which penetrate through the nail plate to give relief to fungal symptoms. Look for products which feature a ‘transdermal delivery system’ because this means it will work on the area under the nails where fungus thrive.
There are other conditions that might cause yellow nails such as psoriasis or thyroid diseases (in rare cases), and chronic bronchitis.
