Question 1

what can cause fingernails and toenails to turn blue?

Accepted Answer

It could be...: A lot of different things, but circulation disorders will cause this.  See your pcp or a vascular specialist for more detailed evaluation and treatment.

Question 2

can flu-like symptoms suddenly cause your fingernails to turn blue?

Accepted Answer

Not likely: Nails or skin under nails?  I can not think of a way to change color of your nails, but skin under nails typically reflects amount of oxygen being carried by red cells. Bright red means full of oxygen and blue means depleted. Other disorders can also cause discoloration, but if new or associated with shortness of breath will need an explanation soon.

Raynaud's: Raynaud's disease can cause this.  It is a temporary vasoconstriction of the small arteries in the fingers and toes triggered by cold.

Question 4

what causes ridges in yourfingernails?

Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex.

Question 8

any reasons why my fingernails turn blue easily?

Accepted Answer

Circulatory issue: You may have a deficiency of the circulation to your fingers or a sympathetic nerve issue.  This may be part of a condition termed Raynaud's phenomenon.  Whatever the cause, it is best to bring this to the attention of your family doctor who can make a diagnosis for you.

Question 9

what causes fingernails to fall off occasionally?

Accepted Answer

Varies: The cause of fingernails falling off can be secondary to trauma, infection, or other systemic diseases.

Question 10

what would cause horizontal ridges on fingernails?

Accepted Answer

Beau's lines: Beau's lines, which are grooves that run horizontally across the nail plate. They usually develop when nail plate growth, which begins in the nail matrix (located under the cuticle), is temporarily disrupted. This can occur with direct injury to the nail matrix; an inflammatory condition such as psoriasis; infection around the nail plate; repetitive picking at the nails or cuticles; or sickness.
