Fungal infection in the nails is caused by an overgrowth of fungi in your nails. When the growth of fungus happens on the fingernails or toenails, it is known as onychomycosis or tinea unguium. Here are the probable causes of why you might get a fungal nail infection:

1. Diabetes
2. Problems in your circulatory system
3. Age
4. Artificial nails
5. Swimming in public pools
6. Nail injuries
7. Skin injuries surrounding the nail
8. Fingers or toes, which have been moist for an extended period of time
9. Immune system problems
10. Wearing shoes which have enclosed toes

It is also worth noting that fungal infections happen much more frequently in your toenail as compared to your fingernails, this is because of two main reasons. Firstly, that the fungi can grow very easily on your toenails because of the position as your shoes are dark, warm and moist and therefore, perfect for the growth of fungi.

The second reason for more fungal infections on your toenails as compared to your fingernails is because toes have less blood flow than fingers, thus making it harder for the immune system to fight off the infection.

Fungal infections in your nails are one of the easier infections to diagnose. This is because there are several symptoms which indicate you have this condition. 

Here are some of those symptoms:
1. Scaling underneath your skin
2. White or yellow streaks on your nails
3. Corners of the nail may crumble
4. Flaky surface of the nail
5. Yellow spots at the bottom of the nails
6. Loss of nail
7. A nail breaking off from the rest of the nail
8. An odor from the nail
9. Brittle or thick nails



Causes and Symptoms of Fungal Nail Infection

Nail fungus is a very common problem. Symptoms include inflammation, swelling, yellowing, thickening or crumbling of the nail. It is usually not painful, unless the infection spreads. If left untreated, nail fungus can cause cracking, splitting and even complete loss of the nail. The good news is that nail fungus is curable and can be treated very easily. There are many specialized treatments required for bringing quickest recovery. Most people think that medications are the only solution in this regard, but this is not true as there are many therapies that are needed along with medicines so that speed of recovery can be boosted to a great extent.

Treatments for fungal nail infections
1. Antifungal medications: Nails are first tested thoroughly in order to get the confirmation about nail fungus. Both growth and reproduction of fungal cells are prevented by consuming these medications. Some of these medicines are used for topical or external application while others are taken orally. Some of the physicians suggest continuing, both types of medicines simultaneously for getting more powerful effects and quick recovery. However, there are a few probable side-effects that occur while taking these medicines and these include loss in taste, rashes, diarrhoea, itching, headache and others.

2. Using antifungal nail-paint: Nowadays, you can use antifungal nail-paints so that the deepest layer of the nail can be well treated and infected parts can be healed quickly. But you have to continue the usage for a few months, or else, you will not be able to get the desirable results.

3. Laser treatment: This treatment is one of the most powerful ones and can treat your infected nail with greater speed and accuracy. Light energy in high doses is used for treating nail infection in this case.
The above treatments are really quite helpful, and you can choose any of them as per your necessity, preference and affordability.

Things you can do at home
1. Keep your hands and feet clean and dry
2. Wear well fitting shoes made of natural materials and clean cotton socks, these will allow your feet to "breathe"
3. Clip your nails to keep them short, use a separate pair of clippers or scissors for the infected nail
4. Don't share towels and socks with other people, and ensure your towels are washed regularly
5. Don't walk around barefoot in public pools, showers, and locker rooms, special shower shoes are available to protect your feet
6. Consider replacing old footwear as it could be the source of the infection
7. Treat athlete's foot as soon as possible to avoid the infection spreading to your nails

How to Treat Fungal Nail Infections?

Your nails tell a lot about your health or the lack of it! Many health problems have nails as the indicators or warning signs. If your nails are not healthy or pink and shiny, you might be in for some sort of health issue.  If you have cracked nails, discoloured nails, irregularities or very thick nails then you probably have some internal health problem.

Look for these indicators to get an idea-

1) Color of your nails : Pink or white nails are considered healthy. Dark spots on your nails? surface are not just a sign of aging but also indicate a risk of heart disease. Red color is a possible sign of heart infections and green colour usually indicates local fungal infection.

2) Brittle nails: If your nails are brittle and get cracked often, it is due to lack of folic acid, vitamin C and protein. In 10% of cases, psoriasis starts with the nails.

3) Furrow nails: Furrow nails are the ones which are irregular with a dent like appearance. It may indicate you of psoriasis or auto-immune illness which leads to hair loss. Thick furrow nails may signal a yeast infection.

4) Thick nails: Nails thicken in time. Thick nails are neither natural nor normal. If your nails are extremely thick, you probably it could be that your lungs are not healthy. It can also indicative of the fact that your body has poor circulation.

5) Curved nails: If your nails are curved and concave like shape it might signal either lack of iron or heart problems.



What Your Nails Tell About Your Health

Have you ever come across a person with usual toes, toes that are mysteriously curled or bend upwards, downwards or inwards? As strange and intriguing as it may appear, the condition can be quite painful and is known as toe deformity. In toe deformity, the foot bone is unusually and abnormally positioned, resulting in pain and discomfort.

Toe deformity in a person can be of different types. It can be:

Hammer toe: This is one of the most commonly observed toe deformity. A hammer toe is characterized by the curling or bending down of the second toe at the proximal interphalangeal joint (the middle toe joint). The toe may further bend up at the distal interphalangeal joint (joint adjacent to the toe tip) or the metatarsophalangeal joint (meeting point of the foot and the toe) as well. In hammer toe, the awkward alignment results in a slight elevation in the joint of the middle toe. A hammer toe is often seen accompanied by a bunion (a bony bump or a deformity formed at the joint that links the foot with the big toe).
Mallet toe: Mallet toe mostly affects the second toe (other toes may be affected). The deformity results in bending down of the toe at the distal interphalangeal joint (appears like a mallet).
Claw toe: The deformity affects all the toes, with the big toe being an exception. Here, the toes bend up at the metatarsophalangeal joint and bend down at the distal interphalangeal joint. The deformity results in the toes curling down towards the floor (appears claw-like).
What causes Toe Deformity?
There can be many factors responsible for toe deformities.

Toe deformity in a person may be congenital (present from birth).
It can also be an outcome of medical conditions such as arthritis (osteoarthritis, rheumatoid arthritis), stroke, heart attack, diabetes, an injury, an accident, or wearing wrong footwear.
Toe deformity can also be hereditary.
Signs and symptoms:
The symptoms for Toe Deformity (hammer toe, claw toe, and mallet toe) include

There is redness, pain, and swelling in the affected part of the toe. In claw toe, however, there may or may not be pain associated with the condition.
A person faces difficulties in straightening the toe.
In hammer toe, corns, and calluses appear on the middle joint (top) of the affected toe.
In mallet toe, ulcers may occur on the toe (in diabetic patients).
Treatment:
Initially, toe deformity appears flexible, where movement around the affected joint is possible. However, if left unattended, the condition can become severe and rigid, thereby restricting the movement (in the affected area). Treatment for toe deformity depends on how severe the condition is.

In most cases, the treatment involves wearing custom-made shoes, fitted with supports (cushions or pads) and wider toe box.
Using of tapes and splints may be helpful in correcting and repositioning the deformed toe.
Patients with excruciating pain benefit immensely from cortisone injections.
Corn pads can be used to deal with corns and calluses better.
Toe stretching exercises are highly effective.
If severe cases or extreme rigidity, doctors may opt for surgical treatments like arthrodesis, tendon transfer, arthroplasty, to name a few.

Toe Deformity- What Causes It And What Are Its Treatment Options?

Nails are an important part of your physiology, although they are mostly used for either utilitarian purposes such as gripping or for beauty purposes such as nail decorations. Nails themselves can go through infections which need not have underlying causes and thus can cause damage to that part of the tissue. One such disorder of the nail is onycholysis.

What is onycholysis?
This is a disorder where the nail on the finger or the toes starts to separate from the skin below. This happens little by little and usually starts at the tip and then progresses backward. The further back it progresses, the more nail tissue it destroys. While the entire nail may not be detached from the nail bed, parts of it may chip off, showing the tissue underneath.

Symptoms of Onycholysis:

Jagged border between the pink flesh of the nail bed and the yellow edge of the nail
Detached nails become opaque, yellow or may turn green in color
Nail may become irregular in shape and size
Bits and chunks of nails can break off easily
Primary Causes for Onycholysis:

Frequent trauma - If you have a profession or work at home where you constantly require tapping away, it might cause minute injuries to build up within the nails and the fingers. Tapping on keyboards is one area where you could get repetitive trauma like this.
Manicure problems - Many salons may aggressively try to clean the underside of the nails and in the process, slowly dislodge the nail form the nail bed and cause onycholysis. This has known to be the case with many people.
Water immersion - If you have work where your nails are immersed in water for long periods of time, this could also affect the development of onycholysis.
Skin diseases - Certain skin conditions can also end up giving onycholysis. Psoriasis and contact dermatitis are other conditions that may lead to onycholysis as a consequence.
Allergy to nail glue - Many makeup artists and customers have complained that certain brands of nail glue can also cause allergies resulting in onycholysis.
Medications - Medications meant for the treatment of other ailments within the body can have the unintended consequences of causing onycholysis.
Treatment:
The underlying problems need to be corrected which may cause onycholysis. Once the underlying problem is corrected, onycholysis usually corrects itself. The nail may take some time to re-grow but will grow back on its own eventually and may take 4 to 6 months to cover the entire affected area again.

Onycholysis - How It Can Affect Your Nails?

If you are experiencing symptoms such as swelling, inflammation, thickening, yellowing and crumbling of your nails, toenail fungus or onychomycosis is indicated. This is a very common problem, which is usually painless, unless the infection gets spread. The fungus thrives under certain conditions like abnormal levels of pH in the skin, a weak immune system, poor hygiene, diabetes and a continuous exposure to moist or damp environment. If not treated properly, toenail fungus can lead to cracking, splitting or total loss of your toenail. There are various ways of treating fungal infections in the nails. Some of them are as follows:

Tea Tree Oil: Tea tree oil contains antiseptic and antifungal properties, which help in treating toenail fungus. You need to mix some drops of tea tree oil with coconut oil and olive oil. Using a piece of cotton, apply the mixture on your affected nail, keep it for 10 minutes and scrub off the nail with a toothbrush. For ideal results, you must repeat this process more than twice regularly.

Baking Soda: Baking soda is a commonly used remedy for fungal infections in your nails. It also helps in neutralizing foot odor. Add baking soda, hydrogen peroxide and Epsom salt in hot water, add vinegar to the mixture and soak your affected nail in the solution. After this, wash your feet with water. Repeat the procedure twice a day for several weeks.

White Vinegar: This is an ideal ingredient for the treatment of toenail fungus. It helps in restoring the pH balance of the skin and fights against infections. Add one part of white vinegar to warm water and soak your affected toenail in it for about 10 minutes. After this, you must wash it off. Carry out the process twice a day for effective results.

Oil of Pregano: Oil of oregano is considered effective because of its antibacterial, antiviral, analgesic and antiseptic properties. It is an ideal way for treating fungal infections in your nails. Mix oregano oil with olive oil, apply the solution on your nails and leave it for over 30 minutes. Repeat the process thrice a day for good results.

Listerine Mouthwash: Listerine mouthwash is another important home remedy for treating fungal infections in the nails. This mouthwash contains certain compounds along with alcohol, which have very strong antiseptic properties and help in eliminating harmful fungi and bacteria from your nails.
