If toenail fungus enters the bloodstream, it's rare but serious, potentially causing widespread infection (fungemia), leading to sepsis (blood poisoning) and organ damage, especially in people with weakened immune systems, like diabetics. While usually localized, untreated severe fungal infections can sometimes become systemic, requiring prompt medical attention to prevent life-threatening complications like sepsis, which causes fever, chills, weakness, and low blood pressure, with a significant risk of mortality.
Once the yeast fungus enters the bloodstream, it can cause blood poisoning (sepsis), leading to permanent damage to internal organs: One-third to one-half of patients do not survive such fungal sepsis. The natural response of the immune system to the invasion of pathogens is an inflammatory reaction.
For pregnancy-safe toenail fungus treatment, consult your doctor for options like topical antifungals (clotrimazole, miconazole), which are generally preferred, or laser therapy, a medication-free choice; avoid oral medications unless necessary, and consider home remedies like Epsom salt soaks or tea tree oil (diluted, with professional guidance) while waiting for professional care, as oral antifungals and some natural remedies carry risks.
While rare, severe cases of toenail fungus can potentially lead to systemic infection, especially in individuals with compromised immune systems. In such cases, the fungus may enter the bloodstream and spread to other parts of the body, including vital organs.
A severe case of nail fungus can be painful and may cause permanent damage to your nails. And it may lead to other serious infections that spread beyond your feet if you have a suppressed immune system due to medication, diabetes or other conditions.
And, if the infection continues to be left untreated, it can even enter the bloodstream and cause a serious condition, such as sepsis or gangrene. If you have diabetes, you're at greater risk for developing complications from ingrown toenails.
Poisons: Arsenic poisoning may cause white lines and horizontal ridges. Silver intake can cause a blue nail.
If toenail fungus goes untreated, it worsens, causing the nail to thicken, discolor (yellow/brown), become brittle, crumble, and potentially separate from the nail bed, leading to pain, odor, and difficulty walking; it can spread to other nails/skin (athlete's foot) and, in rare cases, lead to serious bacterial infections like cellulitis, especially for those with diabetes or weakened immunity, potentially causing permanent nail damage or systemic issues.
The toe-to-heart connection
Your toes are at the very end of your circulatory system, which means fungus has a direct path back to your heart. Treating your toenail fungal infection at the source helps prevent it from circulating back to the heart, where it might otherwise lead to an even worse infection.
If cellulitis is left untreated, the infection can spread to the bloodstream and become a life-threatening condition for many individuals. This is the most serious result of an untreated toenail fungus, which can be avoided with treatment from a medical professional.
To permanently kill toenail fungus, you need professional treatment, with oral antifungal medications like terbinafine (Lamisil) being the most effective for clearing the infection, though they require months of use and liver monitoring. Prescription topical creams (e.g., Jublia, Kerydin) and medicated nail polishes (Penlac) are also options, often used with nail thinning or combined with oral meds. Laser therapy can be effective by heating the fungus but isn't a first-line treatment and lacks strong evidence for a permanent cure.
To use it, apply Vicks VapoRub with a cotton swab and try to work it under the nail a bit, Dr. West says. Put a sock on to keep the product in place. Repeat at least three to four times per week, though daily is safe, too.
Diabetics are also prone to toenail fungus, which leads to discolored, thickened, and brittle nails. To manage these issues, it is essential to practice good foot hygiene, including regular nail trimming and keeping feet clean and dry.
Symptoms of sepsis may include:
Bloodstream infections caused by the fungus Candida are among the most common and deadly infections in hospitals, with 25,000 such cases seen annually in the U.S. – mostly in people originally hospitalized for other reasons. About 40% to 45% of people with Candida in their blood die of the infection.
Stage 3: Advanced Infection
In the advanced stage, fungal toenail infections can cause severe changes, including: Extensive nail discoloration and deformity. Severe thickening of the nail, making it difficult to trim. Pain and potential complications like secondary bacterial infections or ingrown toenails.

Three early warning signs of heart failure include persistent fatigue/weakness, shortness of breath (especially with activity or lying down), and swelling (edema) in your legs, ankles, and feet, often accompanied by rapid weight gain from fluid buildup, all signaling your heart isn't pumping efficiently enough. Other key indicators are a chronic cough (sometimes with pink mucus) and heart palpitations.
Fungal infections can occur anywhere in your body but most commonly, they begin on your skin. Most cause some discomfort, such as redness and itching. Usually over-the-counter or prescription medications take care of this. Sometimes these skin infections do not heal though and they worsen, possibly causing sepsis.
Sometimes, toe fungal infections can be severe and require medical intervention. This is especially true if a person has diabetes or a compromised immune system. Contact your podiatrist immediately if you or your loved one are at higher risk and suffering from fungus toenails in (or near) Suffolk or Norfolk, VA.
A podiatrist can treat the infection effectively and thoroughly with prescription anti-fungal medications and creams. They may alternatively use a special laser that passes light energy through the nail and under the nail bed to target and eradicate the fungi.
Dermophytes can also cause ringworm and fungal scalp infections. Toenail fungus doesn't usually spread to inside your body, like the stomach. The fungi require keratin, found in your hair, skin and nails. They survive best on the skin.
Look how strikingly pale the nails are. Normally, your nails have a pinkish color because of the tiny blood vessels that are in the tissue underneath your nail. But in liver disease, there are changes to that tissue which makes it difficult to see the tiny blood vessels and that's why the nails are so pale.
Common toenail abnormalities include discoloration, thickening, and detachment, often linked to underlying health issues. Conditions like anemia, diabetes, and autoimmune disorders can manifest as changes in nail appearance or texture.
Keratin granules are areas of damage to the top layers of the nail. They show up as small, chalky white spots or rough patches and happen when nail polish, especially if left on too long, dries out and weakens the surface of the nail.
