🧠 15 Common but Overlooked Causes of Itching

1. Diabetes

Peripheral neuropathy → poor blood circulation → nerve degeneration → itching , burning, stinging pain

2. Polycythemia

Too many red blood cells → Thick blood → Skin hypoxia → Itching

3. Parathyroid dysfunction

Excessive calcium → calcium deposits on the skin → irritation of nerve endings → itching
Some people experience relief from itching after parathyroidectomy.

4. Uremia

Kidney function decline → urea accumulation in the skin → nerve irritation → chronic itching

5. Liver and gallbladder problems (cirrhosis/cholestasis)

Bile salts cannot be excreted normally → accumulate into bile sludge → irritate skin nerves
Common symptoms: right upper abdominal distension and pain + right scapular pain

6. Vitamin A / D deficiency

Insufficient bile → Inability to absorb fat-soluble vitamins → Dry skin + inflammation

7Omega-3 deficiency

In modern humans , the Omega-6 to Omega-3 ratio is as high as 20:1, leading to inflammation and itching.
It is recommended to supplement with deep-sea fish oil and flaxseed oil.

8 Microbial Infections

Head lice, scabies, hookworms, Candida, bed lice, tinea, etc. → localized itching

9. Poison Ivy

Severe allergic reaction → spreading itching + redness and swelling
A hot shower can provide temporary relief (approximately 3 hours).

10 Ticks

Initially, there was no sensation → later, localized itching and red circles appeared ( Bullseye ).
Be aware of the possibility of Lyme disease .

11 Hormonal imbalance

Estrogen/thyroid hormone abnormalities → altered skin sensitivity

1️2 Drug side effects

Some medications (such as painkillers and antibiotics) can cause itchy skin.

13 Food allergies

Allergic reaction to certain foods (such as seafood and nuts) → itching reaction

14. Mental stress

Emotional stress → Increased skin nerve sensitivity → Increased itching

15. Neurogenic Itch

Central nervous system error signal → Persistent itching without obvious skin lesions

🧂 Natural remedies for itching

TUDCA (Taururose Deoxycholic Acid) : Dilutes bile → Reduces biliary sludge → Relieves hepatobiliary itching
Supplementing with Omega-3 : Deep-sea fish oil, flaxseed oil
Supplementing with Vitamins A and D : Improves skin barrier and reduces inflammation.
Improve your diet : reduce sugar, reduce processed oils, and increase vegetables and healthy fats.

🧠 Why does scratching feel so good?

Scratching releases serotonin and dopamine .
It provides temporary relief but may worsen skin irritation → It is recommended to use cold compresses/hot water/natural anti-itch creams instead.

🧾 In conclusion: Don't assume that "scars = skin problems" anymore. Understanding the root cause is key to truly stopping the itching.

Starting today, a liver-protecting diet, a strategy for supplementing with fat-soluble vitamins, and a targeted anti-itch solution will lay a solid foundation for your skin's nerve function!

Don't be misled by the idea that "applying ointment equals solving itching." True health comes from understanding how to regulate, supplement, and avoid certain areas! 💪🧠🩺
