Caída del pelo tras una dieta rápida o una cirugía bariátrica: por qué empieza meses después

Hair loss after rapid weight loss or bariatric surgery: why it starts months later

If your hair starts falling out months after losing weight quickly or having surgery, the most likely cause is telogen effluvium. This is diffuse, non-scarring hair loss that shows up late because of the way the hair follicle cycle works. We explain why it happens, which nutrients matter most and what the evidence says.

Hematocrito alto con testosterona: a partir de qué cifra preocupa y cómo se controla

High haematocrit on testosterone: what level is a concern and how it is monitored

Testosterone can raise your haematocrit. Above 52% it counts as erythrocytosis, and the Endocrine Society sets 54% as the level at which treatment is paused. Here we explain why it happens, what the measured risk actually is and which follow-up blood tests are done in Spain.

¿Puedo tomar terapia hormonal si tengo trombosis, hipertensión o sobrepeso? Cuándo se puede y con qué vía

Can I take hormone therapy if I have had a thrombosis, or have high blood pressure or excess weight? When it is possible and which route to use

If you have high blood pressure or excess weight, menopausal hormone therapy can usually still be considered, and guidelines prefer a patch or gel. A previous thrombosis changes things. We explain what the studies show, why the route matters so much and what the Spanish summaries of product characteristics say.

Mejor clínica online para perder peso en España (2026): qué comparar y qué exigir

Best online weight loss clinic in Spain (2026): what to compare and what to expect

No single online clinic is the best for everyone. What you can do is compare them sensibly. Look for a proper medical assessment, a doctor you can identify, the genuine medicine obtained legally, follow-up, a clear price and a plan that goes beyond the drug. This guide covers what to expect from a clinic, what results the trials show are realistic, and the signs that a clinic isn't trustworthy.

Clínica capilar o telemedicina: qué cambia en el diagnóstico, el seguimiento y el precio

Hair clinic or telemedicine: what changes in diagnosis, follow-up and price

For typical androgenetic alopecia, remote hair consultations get the diagnosis right in the vast majority of cases. Types of hair loss that need trichoscopy still call for an in-person appointment. We look at what the studies say about diagnosis, why follow-up timelines are the same in both settings and what can honestly be said about price.

Saxenda precio en España: coste real al mes y cómo se compara

Saxenda price in Spain: the real monthly cost and how it compares

Saxenda is not funded by Spain's National Health System: the 5-pen pack costs €283.05 and the 3-pen pack €185.81. We explain how many days each pen covers depending on the dose, why comparing pack prices with Wegovy or Mounjaro is misleading, and what STEP 8 says about cost per result.

¿Qué analíticas te piden antes de recetar testosterona en España?

Which blood tests do you need before testosterone is prescribed in Spain?

One low result is not enough to justify a testosterone prescription. Guidelines require morning, fasting total testosterone, repeated on different days, plus symptoms that fit and a safety check that includes PSA and haematocrit. We explain each test, what it is for and what is known about how it is used in Spain.

Resistencia a la insulina: síntomas, diagnóstico y qué se sabe que la revierte

Insulin resistance: symptoms, diagnosis and what is known to reverse it

Insulin resistance is the central mechanism behind disorders of glucose metabolism, yet it has no standard diagnostic test and no validated list of symptoms. What has been measured is what happens when weight comes off: in DiRECT, 46% of participants with type 2 diabetes achieved remission at one year, rising to 86% among those who lost 15 kg or more.

Androgenetic alopecia in women: why it's different and what options exist in Spain

Finasterida precio en España: coste real al mes con y sin marca

Finasteride price in Spain: the real monthly cost, branded and generic

In Spain, finasteride 1 mg for hair loss is prescription-only, and you should not assume it is funded by the National Health System. There is no verified official retail price (PVP) in the facts available, so the real cost is easier to understand by pack size and how long each pack lasts. At 1 mg a day, a 28-tablet pack lasts just under a month and a 98-tablet pack lasts just over three months.
