“Without a doubt the best proctologist I’ve seen in recent years, and I’ve seen several! She was the only one who made me feel safe and took away my fear of surgery, which, by the way, was the best choice I’ve ever made. I have a whole new life.”
Hemorrhoid treatment: effective, discreet relief
Dr. Luiza Pettinelli · CRM-SP 212.349 · RQE 102.999Get your quality of life back with personalized hemorrhoid treatment — often without surgery, always with discreet, specialized care.

Up to half of Brazilian adults suffer from hemorrhoids
With early treatment, it can be resolved less invasively and greatly improve quality of life.
Constipation
Straining to pass stool increases pressure on the veins in the anal area and can cause or worsen hemorrhoids.
Family history
Genetic factors can predispose people to hemorrhoids, even at a younger age.
Excess weight
Being overweight increases pressure on the veins in the anal area.
Pregnancy
The enlarged uterus and hormonal changes of pregnancy make hemorrhoids more likely to appear.
Don't wait for a flare-up to get worse
Thrombosed hemorrhoid
A clot in a hemorrhoidal vein, with intense pain, swelling, and a purplish lump. It requires prompt medical attention.
Rectal bleeding
Bright red blood on the paper or in the toilet bowl after a bowel movement. Persistent bleeding can lead to anemia — and needs to be investigated.
Anal fissure
Small tears in the anal canal that cause sharp pain during bowel movements, often as a complication of untreated hemorrhoids.

Feel good again
Quality of life: free of pain and with regular bowel movements.
Easier hygiene: easier cleaning, less irritation and more comfort.
Self-esteem: without the constant worry and embarrassment.
Prevention: blood in the stool can have other causes — the evaluation rules out more serious conditions.

I recommend her not only for her professionalism but also for her compassionate care!”

Hemorrhoids
Do I need to prepare for the consultation?
No. You can come as usual, even if you're on your period — it doesn't prevent the assessment in any way.
How is it diagnosed?
With anoscopy, a painless in-office exam that shows whether hemorrhoids are internal or external and what grade they are. Treatment is then recommended based on it.
Do hemorrhoids go away on their own?
Unfortunately not. The inflammation may go down and symptoms may ease for a while, but it tends to get worse if left untreated.
Is there a non-surgical treatment?
Yes. Rubber band ligation, done in the office, resolves many cases. Surgery is reserved for more advanced cases — and, when needed, techniques such as laser and botulinum toxin help reduce pain.
